Atoms, Elements, & Compounds
Atoms & ElementsAn atom is the basic unit of
matter (make up elements) If you break it any smaller it is no
longer the elementAtoms are made up of smaller
pieces called protons, electrons, and neutrons
Elements are made entirely of the same type of atom
BondingWhen two or more atoms are
joined together they form a bond
There are two types of bonds between atoms, ionic and covalent
Molecules & SaltsTwo or more atoms joined
together form a compoundThe two main types of
compounds are molecules and salts Molecules are formed from covalent
bonds (shared electrons) Salts are formed from ionic bonds
(taken electrons)
Hydrogen BondingA third type of bonding, called
hydrogen bonding, occurs between certain molecules
Very present in water
