It depends on the types of atoms that are reacting.
An atom that has gained an electron becomes a negatively charged ion.
surely i don't know sodium atom which can be gained 2 electrons but anyway i thought the answer is Na+2
anion
An ionic bond is formed when electrons have been lost by one atom (to become a positively charged ion) and gained by another atom (to become a negatively charged ion), resulting in an attraction between the oppositely charged ions.
An electron can be gained or lost from an atom for two reasons: 1. A random number of atoms can be close together will have electrons bumping into each other. Since all electrons have a negative charge, they will have magnetic effects on one another, and will push eachother of the outer shell of their atoms and into different ones. 2.Two or more atoms can bond together so that both atoms in turn have a balanced number of electrons.
anion
Positive
When an atom is ionized, that means that it is sharing one or more electrons with another atom.
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
It is a negative charge
An ion
