Anions are negative ions that are formed when a nonmetal atom gains one or more electrons. Anions are so named because they are attracted to the anode (positive field) in an electrical field. Atoms typically gain electrons so that they will have the electron configuration of a noble gas.

What is an anion?
Anions are negatively charged ions. They are formed when non-metal gains the electrons. They gain one or more than one electron. Therefore, they possess a net negative charge. Some examples of anions are Iodide (I–), chloride (Cl–), hydroxide (OH–).

What is an example of anion and cation?
Oxygen often exists in a neutral state, but oxygen atoms tend to form anions by gaining two electrons. Atoms of other elements also tend to form anions, including nitrogen, chlorine, and fluorine, among others. By contrast, atoms of calcium, magnesium, aluminum, and sodium tend to lose electrons and form cations.

Is oxygen is an anion?
Oxygen has 6 valence electrons on the structure and will gain 2 electrons to achieve a complete octet. Since Oxygen will gain 2 electrons, it will exist as O2− ion. The given ion is considered an anion since it is a negatively-charged ion.

What is cation and anion with example?
Some examples of anions are Iodide (I–), chloride (Cl–), hydroxide (OH–). When sodium a cation is depicted as Na+, the plus charge indicator shows that it has one electron less than the total number of protons. Thus, sodium having an uneven distribution of electrons and protons enables it to have a positive charge.

Is anion positive or negative?
An anion is an atom that has more electrons than protons—in other words, an anion is an atom with a negative charge. In a chemistry class, you’ll come across the word ion frequently. That’s an atom that either has extra electrons, giving it a negative charge, or is missing electrons, resulting in a positive charge.
