| What is the smallest element | atom |
| the atomatic number of an atom indecates the number of | protons |
| The particles involved in the transever or sharing between atoms are the | valence electrons |
| the zig-zag line, on the periodic table, seporates the metals from the non-metals. the elements that are found on both sides of the zig zag line are called | metalloids |
| elements that have similier properties and the same amount of valence electrons are classified as | a group of a family |
| an elements properties can be predicted from its | location on the perodic table |
| which of thje fllowign is NOT a charicterristic of most metals | brittle |
