Metals?
An atom with the
same number of
electrons in the outer
shell as Mg.
What is Be, Ca?
This family is the only
family on the periodic table
that does NOT react with
any other element.
What is the noble
gases because they
have a full outer
ring of electrons?
The atomic
number of an
element tells you
this.
