Naming Groups in the Table
And a Few Vocabulary Terms
Vocabulary Terms


Malleable- Metals are malleable, which
means they can be hammered or rolled
into sheets like aluminum
Ductile- Metal that can be drawn into wire
like copper
Terms cont.


Metallic Bond- When metals bond with
themselves or with other metals they do
so with metallic bonds
These electrons in metallic bonds move
freely. Movement of electrons gives us
____________?
Terms cont.


Radioactive- Elements that breakdown
easily. Most of the lower elements in a
group are radioactive. (Francium and
Radon)
Transuranium Element- All elements after
uranium (Atomic # 92)
Can you name 5 of them?
Terms cont.

Diatomic molecule- O2, H2, N2 are
examples. Two atoms of the same
element together
