When the element bonds with another element it accepts electrons (it does not give them away) and becomes negatively charged.
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).
It is neither acidic, nor basic. It even isn't an anion: element Chlorine is Cl2.
No, an anion does not always form a covalent bond. An anion can form both ionic and covalent bonds depending on the nature of the element it is bonding with. In an ionic bond, an anion will typically form a bond with a cation through the transfer of electrons, while in a covalent bond, an anion will share electrons with another element.
The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.
Selenium is an non-metal element that can exist in various oxidation states, including as a cation (Se^2+) or an anion (Se^2-, Se^4-, etc.). The oxidation state of selenium determines whether it acts as a cation or anion in a given compound.
Br is an anion. It is called bromide and is the ion form of the element bromine.
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).
Oxygen is an element. It normally forms anions.
It is neither acidic, nor basic. It even isn't an anion: element Chlorine is Cl2.

Cesium is a cation, as it has a positive charge due to losing an electron.
Selenium is an non-metal element that can exist in various oxidation states, including as a cation (Se^2+) or an anion (Se^2-, Se^4-, etc.). The oxidation state of selenium determines whether it acts as a cation or anion in a given compound.
Fluorine is an element. Fluoride is an anion.
Non metals generally form anions. They gain electrons during ionic bonding.
This is a polyatomic anion.
Gallium is a metallic element. It forms cations Ga3+ and Ga+
