Elements that occur in vertical columns on the periodic table.
an element that has both metallic and nonmetallic properties
not able to conduct heat or electricity, little to no metallic luster
found in group one of the periodic table; highly reactive
How many valence electrons does a carbon atom have?

Why are halogens so reactive?
They want to get rid of their only valance electron
They only need one more electron
They are non reactive, they have a full shell
