Chemical Bond

the attractive force holding atoms or ions together to form molecules or compounds

Covalent

relating to or denoting chemical bonds formed by the sharing of electrons between atoms

Ionic Bond

a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Metal 

Elements found on the left side of the table are characterized by their ability to lose electrons to form positive ions
