What are ionic and covalent bonding?

Answer 1

An ionic bond, an electron is simply transferred to another atom bound together by the attraction between oppositely-charged ions.

A covalent bonds is bound together by the sharing of electrons.

See attached links for a picture and for more information.

Answer 2

Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of positively and negatively charged ions that are attracted to each other. Covalent bonding involves the sharing of electrons between atoms to achieve a stable electron configuration.

Answer 3

Ionic bonding means that the electrons are transferred: NaCl (usually between elements in the 1st and 17th group).

Covalent means that the electrons are being shared: CH4.
