1
These elements are dull, brittle and are poor conductors of heat & electricity
Metals
Metalloids
Halogens
Nonmetals
2
What number gives the number of valence electrons for an element?
Group Number
Atomic Number
Number Under Group Number
Atomic Mass
3
This is used to calculate the number of neutrons.
Mass Number (-) the Atomic Number = # of Neutrons
Mass Number (+) the Atomic Number = # of Neutrons
Atomic Number (-) Period Number = # of Neutrons
Atomic Number (-) the Group Number = # of Neutrons
