Types of bonds
There are 3 types: ionic, covalent, and metallic bonds
These bonds form from the electrical attraction between large numbers of cations and anions.
In the simplest case it is a bond between a nonmetal and a metal.
Ex: NaCl, Sodium (metal) and Chlorine (nonmetal)
these bonds are formed by the sharing of one or more electrons between atoms.
Usually between 2 nonmetals.
Ex: C10H8, Carbon and Hydrogen (both nonmetals)
These bonds are formed from the attraction between mobile electrons and fixed, positively charged metallic atoms. It's the force that holds atoms together in a metallic substance.
Also formed by only metal's ions
Ex: C, Copper
