Matter: Anything that takes
up mass and takes up space
Compounds
Substance made of more than one Element
They are typically represented by
chemical equations
They are formed by Ionic and
Covalent Bonds
Covalent Bond is when electrons are shared
between to moleculres
Ionic Bonds is when the extra electrons
are transferred
Water is H20
Salt is NcCL
Elements
While the same type atoms exist in
all matter, the amount of each particle
varies and therefore makes different
substances
Elements are represented by a
symbol
Hydrogen is H
Iron is Fe
Oxygen is O
All Matter is Made up of Atoms
Atoms are made up of three
subatomic particles
Electrons are surrounding the nucleus
Electrons have a negative charge
Protons and Neutrons are in
the nucleus
Neutrons have a neutral charge
Protons have a positive charge
