Substance that speeds up the rate of chemical reaction
What are the four types of chemical bonds
Ionic Bonds-form when two atoms have a large difference in
electronegativity.
Covalent Bonds-form when two atoms have a very small difference
in electronegativity.
Polar Covalent Bonds- form when two elements bond with a
moderate difference in electronegativity. Fall between ionic and
covalent.
Metallic Bonds-form in and between metals
