Ionic and covalent.

formed when one or more electrons are transferred from one atom to another.<\/p>\n\n\n\n

One atom loses electrons and becomes positively charged. The other gains
electrons and becomes negatively charged. These charged forms are called ions
and are either positively or negatively charged. Na\u207a is an example of a positively
charged ion that has lost an electron. Cl\u207b has gained an electron and is a
negatively charged ion.
How are covalent bonds formed? – ANSWER ~ Covalent
bonds are formed when electrons are shared by atoms, not pulled away
completely.
If the electrons in a covalent bond are shared equally, what is the bond called? –
ANSWER ~ nonpolar covalent
If the electrons in a covalent bond are shared unequally, what is the bond called?<\/p>\n\n\n\n
