What are atoms chemically bonded?

Question

Science project. For my college work.

Answer 1

three types of chemical bonding;

metallic bonding which is exhibited only by metals characterized by a sea of electron they form

ionic bonding is exhibited by ionic compounds, a metal and a nonmetal atom of which the bond is formed due to the opposite charges on atoms upon gaining or losing electrons.

covalent bonding is exhibited by two non metal atoms in which the bond is characterized by sharing of electron to complete an octet of electrons at the outermost orbital of the atom, as opposed to ionic bonding which the electron is completely gained or lost.  

Answer 2

Molecules or ions ("simple" or "complex")
