When an atom gives away its valence electrons, it typically forms a positively charged ion, known as a cation. This process often occurs in ionic bonding, where the electron donor (metal) loses electrons to achieve a more stable electron configuration, while the electron acceptor (non-metal) gains those electrons to become a negatively charged ion, or anion. The resulting electrostatic attraction between the cations and anions leads to the formation of ionic compounds.

Which electrons are the valence electrons of an atom?

What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.

What happens to valence electrons as an ionic bond is formed between a metal and a nonmetal?
At least one, and usually all, of the valence electrons of the metal atom is donated to the valence shell of the nonmetal atom.
If an atom has four valence electrons is it an anion?
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
