Periodic Table

Page 2: CHEMISTRY PART 2 Periodic Table. Chemistry – Recall Chemistry is the study of matter and the changes it undergoes Physical Properties: cause a physical

Chemistry – Recall

Chemistry is the study of matter and the changes it undergoes  Physical Properties: cause a physical change (colour,

density, melting point, boiling point, state of matter)

Chemical Properties: describes how one substance reacts with another

A chemical property can only be identified once a substance has undergone a chemical reaction

Chemical Reaction: where matter changes to produce new substance(s) with properties different from those original materials

Periodic Table

Atomic Number = # of protons

If the atom is neutral: Atomic Number = # of electrons

Atomic Mass = # of protons + # of neutrons

# of neutrons = atomic mass - # of protons

Periodic Table

Elements are in order of increasing atomic mass.
