Cations are formed by the loss of electrons, anions are formed by the gain of electrons. The force of attraction between cations and anions results in ionic bond.
The electrons that form bonds are called valence electrons. These electrons are in the outer most shell of an atom.
valence electrons are on the outer shell. they're the ones that will interact with other molecules as bonds are formed. electrons on inner shells don't interact with other molecules. they keep to themselves.
Electrons are transferred when ionic bonds are formed.

The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
When a metallic atom and a nonmetallic atom have an electron transfer to form an ion, this is known as an ionic compound. For example, salt (NaCl) an electron transfer occurs. The Na, which has 1 electron on its valence shell ( outer shell) and the Cl, which has 7 electrons on its valence shell. The Na transfers its one electron to the Cl. This therefore results in the Cl having a full valence shell; at this point Cl is negative and Na is positive. We can then conclude the NaCl is an ionic compound.

At least one, and usually all, of the valence electrons of the metal atom is donated to the valence shell of the nonmetal atom.
Molecules or covalent compounds are formed by the sharing of valence electrons.
Cations are formed by the loss of electrons, anions are formed by the gain of electrons. The force of attraction between cations and anions results in ionic bond.
valence electrons are shared in covalent bonding
Covalent bonds are formed by sharing electrons of the valence shell.
An ionic bond is formed between two atoms by complete transfer of valence electrons from one atom to another atom but a covalent bond is formed between two atoms by the sharing of valence unpaired electrons of both the bonded atoms. An ionic bond is a bond formed between a metal and a non metal. A covalent bond is formed between two non metal atoms.
