Question

Which group of the periodic table has a complete set of valence electrons?

a) group 1, alkali metals
b) group 4, carbon group
c) group 7, halogens
d) group 8, noble gases

I think it's c

Answer 1

When you learn more about bonding, you will come to find that to become stable, atoms loss, gain, or share electrons until their outer shell is filled. (This is usually 8 electrons). The noble gases are extremely un-reactive because they have a complete set of valence electrons. You may learn this as the tendency of atoms to attempt a "noble gas configuration".
