The Difference Between a Cation and an Anion

Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion. Ions are atoms or molecules which have gained or lost one or more valence electrons, giving the ion a net positive or negative charge. If the chemical species has more protons than electrons, it carries a net positive charge. If there are more electrons than protons, the species has a negative charge. The number of neutrons determines the isotope of an element  but does not affect the electrical charge. Cation Versus Anion Cations are ions with a net positive charge. Cation Examples: Silver: AgHydronium: H3OAmmonium: NH4 Anions are ions with a net negative charge. Anion Examples: Hydroxide anion: OH-Oxide anion: O2-Sulfate anion: SO42- Because they have opposite electrical charges, cations and anions are attracted to each other. Cations repel other cations and anions repel other anions. Predicting Cations and Anions Sometimes, you can predict whether an atom will form a cation or an anion based on its position on the periodic table. Alkali metals and alkaline earth metals always  form cations. Halogens always form anions. Most other nonmetals typically form anions (e.g. oxygen, nitrogen, sulfur), while most metals form cations (e.g. iron, gold, mercury). Writing Chemical Formulas When writing the formula of a compound, the cation is listed before the anion. For example, in NaCl, the sodium atom acts as the cation, while the chlorine atom acts as the anion. When writing cation or anion symbols, the element symbol(s) is listed first. The charge is written as a superscript following the chemical formula.

Antigone is an admirable character. How far do you agree...

Antigone is a thoroughly admirable character. How far do you agree with this statement? Throughout the play, Antigone is presented as an audacious and unorthodox female character, whose actions depict her independence and confidence. She dismisses the rules which she believes are false, and honourably battles against her uncles rule to bring justice to her slaughtered brother; her original intentions suggest how important family relationships are to her. However, Antigones reckless behaviour often causes inconsistency in her beliefs. Majorly, nearing the end of her life, she begins to regret all her deeds of which she had once glorified. Antigones initial self-confidence and independence has been replaced with regret and†¦show more content†¦For example, when threatened with the bleak future of a death penalty, her reply that it would be more of an advantage to die. Although her character may not have been expected by an Ancient Greek audience, her unique and unorthodox character (when compared with the typical stereotype of an Ancient Greek woman) would have been admired. Finally, Sophocles shows Antigone to be a passionate religious citizen, who chooses to obey the unwritten, unassailable laws of the divine rather than the short-lived laws of humans. In this way, her undying respect for the gods give her a character similar to a saint or a martyr; she expresses very clearly her acceptance of dying for obeying the words of the gods. This particularly gives Antigone an admirable character, as religion and obeying the gods wishes were viewed as necessities in Ancient Greek life. By showing that she is willing to disobey her own citys king, Antigone appears set to be favoured by the gods for her loyalty. However, Antigones character is very reckless and hotheaded; her swift decisions and ambitious actions often cause contradictory emotions and actions. One prime example relates with the theme of family relationships; Antigone feels that she is noble when honouring [her] own flesh and blood.

Roadside Memorials free essay sample

Roadside Memorials The issue Is roadside memorials and whether they should be allowed on the side of the road or not.

Others believe that people deserve the right to express their grief In any form. This issue had become problematic because the amount of roadside memorials in increasing. Roadside memorials should be illegal because they are a enormous distraction to drivers and . One reason that roadside memorials should be illegal is that they are a distraction for drivers. It Is very Important for a driver to keep their eyes on the road while driving and seeing a roadside memorial can distract the driver and cause them to take their eyes off the road.

Tastes that two vehicles collided along Interstate 5, the drivers apparently distracted by a crowd of more than 100 people who gathered o honor three officers hit by a car at the same location 10 years ago. (Peg. 1) This proves that roadside memorials are distracting because the drivers were distracted and got into an accident. Roadside memorials arent worth another death. One reason that they are a distraction is that people slow down to see what they say or who died. In the same article, Tom Hellman Jar. States that A pickup truck slowed. A station wagon following didnt. People stopping to look at the memorial caused the accident. If the memorial was not placed on the side of the road then the accident would never have happened. In the same article, Dave Thompson Is quoted and he said, Anything that distracts you from driving can be dangerous, (Par, 17). This is very true because drivers get distracted very easily. As a driver you are taught to keep your eyes on the road and not become distracted by other things. Another reason that roadside memorials should be illegal Is that they are littering. In the article, Should roadside memorials be considered littering? It states that At their worst these memorials are indeed litter while at their best they are mere eyesores. When people leave trash on the side to the road they can get tinned. Why are people not fined for leaving memorials on the roadside? They are basically the same concepts. In another article.

(Par. 4) Most families do not come back to clean up the memorials so it makes an even bigger mess ove r time. Littering Is illegal so roadside memorials should be illegal as well. The last reason roadside memorials should be illegal is that most memorials Include a cross and that should not be allowed. In an article from the New York tofu constitutional principle of separation of church and state Crosses are religious symbols and the sides of a highway are public property. Placing a cross on the side of a road is illegal. Churches are allowed to have crosses on their buildings because hey pay for their land. In the Article, Should Roadside memorials be considered littering, it states that society has created a place for memorials upon the passing of a loved one. You may have heard of them: cemeteries. (Par. 2) people should not be forbidden of their right to grief they should be forbidden to express their grief on roadways. There are many other ways to grief in cemeteries. In the same article, it also states that. Cemeteries allow you the opportunity to be as tacky as you like. (Par. 3) there are no restrictions as to what you can place by a gravestone. And there s also no limit to how often you can visit the cemetery. These are all benefits that a roadside memorial does not provide. Death is like the popping or deflating of a balloon. A person is born and throughout their life, they grow and become bigger. Balloons start out really little and then they are inflated and they grow larger. Once a person reaches a certain age, they start to get old and they start to wrinkle and shrink. Balloons can only float around for a certain length of time. After a while they start to shrink and float down to the ground. When a person dies they breathe one sat breath and then everything in them is gone. They are gone and will not be coming back. When a balloon completely deflates it is shrunk down to its original size and no longer floats. All that is left is a wrinkly balloon with nothing inside of it. The deflation of a balloon is a very good analogy for death because it goes through the stages of life and death like a person does. Another way balloons can relate to death is with sudden deaths. Sometimes balloons pop randomly when you least expect it. Sometimes people have heart attacks or other issues that cause them to die unexpectedly. Another way a balloon symbolizes death is when it is popped. The balloon can be full of air and perfectly fine, but someone comes along and pops the balloon and then the balloon is gone forever in a split second. This symbolizes murdering a person. A person can be completely fine one day and someone comes and murders them for no apparent reason and they are suddenly gone. A balloon is a good analogy for life and death for many reasons. The argument of the opposite side is that everyone deserves the right to grieve in whichever way they chose. They believe they have the right to freedom of speech and religion. While they do have the right to freedom of speech and religion, they do not have the right to display their beliefs on public property. Cemeteries were built for people to express their grief openly, and this should be done at a cemetery and not anywhere else. There are many reasons as to why roadside memorials should be illegal and this paper sums all of them up. They are a dangerous distraction, they are considered littering, and they violate the constitution by violating the separation of church and state. Roadside memorials should be illegal because they are not appropriate ways of grieving, and they are very dangerous.
