An element in group 17 will

• gain 1 electron
• lose one electron
• gain 7 electrons
• neither gain or lose because it is inert

An element in group 15

• has 15 valence electrons, and will gain 3 more.
• has 5 valence electrons, and will gain 5 more
• has 15 valence electrons and will lose 7 electrons.
• has 5 valence electrons, and will gain 3 more.

The octet rule states

• that atoms are trying to get a full outershell of electrons
• that some atoms will lose electrons to have a full outershell
• that some atoms will gain electrons to have a full outershell
• all of the above

Electrons in the outermost shell of an atom

• are called valence electrons
• are the only part of the atom involved in bonding
• all of the above
• none of the above
