When an atom gains or loses electrons and therefore becomes an ion, it takes on either a positive or negative charge (positive if it lost electrons, negative if it gained electrons) and can bond to ions of the opposite charge in an ionic bond.
an atom which readily losses or gains electrons to attain stability forms an ion.

An ionic bond.
Beryllium lose electrons (2).
A nitrogen anion forms when a nitrogen atom gains three electrons, forming a nitride ion, N3-.
True. An atom that gains one or more electrons forms a negative ion.
it gains electrons.
No, it looses two electron and becomes Ba2+
An ionic bond forms from the transfer of electrons. The atom that loses one or more electrons forms a positively charged ion, and the atom that gains one or more electrons forms a negatively charged ion. The ionic bond is formed by an electrostatic attraction between the oppositely charged ions.
It gains electrons!
