The energy levels and orbitals the electrons are in
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
l = 1
M1 = -1

The quantum number relating to the size and energy of an orbital
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.
The level of energy possessed by all electrons in one type of orbital
It is a surface of constant probability i.e. an electron is just as likely to be found in a small volume anywhere around this surface. Energy sublevel
