I am shiny and can be pounded flat.
Which element could I be?
O (Oxygen)
F (Fluorine)
He (Helium)
Mg (Magnesium)
I have a dull look (not shiny) and am brittle -- which means I turn into dust if you hit me with a hammer. Which element could I be?

If an atom has 6 valence electrons what will it try to do?
(HINT: Are electrons − or + ?)
gain 2 more and become +2
gain 2 more and become -2
lose all 6 and become +6
