thomaster · Answer

well which 3 actually

thomaster · Answer

Also, look at the positions of these 4 elements in the periodic table at http://ptable.com/ 1 of these elements is grouped somewhere else while the other 3 are all in the same group.

jfraser · Answer

@thomaster is correct, the periodic table groups elements based on similar properties. three of those elements are all found in the same general area. the odd man out must be the answer

ok what about this qustion:why do atoms share electrons in covalent bond?

thomaster · Answer

To gain a full valence shell.
They join together and share one of more electrons so they both have a full outer shell.
