in the 1800’s by Medeleev
are 3 very large groups:
Metals
Non-metals
Metalloids (semi-metals)
Periodic Table Organization
 The
horizontal rows are called periods. Elements in
the same period have the same number of
energy levels / electron shells
 Vertical columns of elements are called groups or
families. Members of each group have similar
physical and chemical properties because of the
number of electrons in their outermost shell.
Group 1 – Alkali Metals

Other Groups
Transition Metals
 The sunken block between groups 2 and 3.
Lanthanides and Actinides
 Removed and found at the bottom of the periodic table.
 Lanthanides are elements 57-70
 Actinides are elements 89-102
 All very rare.
Facts
 Elements
1-92 are naturally occurring.
 Elements 93-102 are man made.
 Hydrogen is the misfit. Like the alkali
metals it has 1 electron in its outermost
shell, but has little else in common with this
group.
