The Periodic Table
Ways the Periodic Table is Organized
Use the Chemical Interactions textbook to describe the following ways the periodic
table is organized. Be sure to give examples as well as the definition:
A: Groups (p. 22)
B: Periods (p. 22)
C: Reactivity (p. 26)
D: Atomic Number (p. 19)
Ways the Periodic Table is Organized
Groups- vertical columns, elements have similar physical properties; Ex. Group 1 contains
Hydrogen, Lithium, Sodium, etc.

Periods- horizontal rows, a proton is added to each element from left to right; ex. Period 2
contains Lithium, Beryllium, Boron, etc.
Ways the Periodic Table is Organized
Reactivity- how likely an element is to undergo a chemical change; Elements in groups 1 and 17
are highly reactive and chemically react easily with other elements

Atomic Number- the number of protons in the nucleus of an atom; the atomic
number increases from left to right; Ex: the atomic number of Hydrogen is 1,
Helium 2, Lithium 3….
