This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons

valence electrons are the electrons in the outermost energy level
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Halogens have six valence electrons in the outermost energy level.
