Periodic Table
Periodic Table Arrangement
groups:
vertical columns are called
groups (numbered from 1→8)
group number = number of
valence electrons
valence electrons→
number of electrons in the
outermost shell
periods:
horizontal rows are classed
as periods
period number = the number
of energy shells used
Metals vs Non Metals
Metals Non Metals
good conductors not good conductors
malleable (can be shaped) brittle
ductile (can be drawn into a wire) not shiny
loses electrons gains electrons
Chemical Reactivity
