The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
The quantum number relating to the size and energy of an 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
You would have to determine the electron configuration for atoms of a given element. Each s sublevel contains 1 orbital, each p sublevel contains 3 orbitals, each d sublevel contain 5 orbitals, and each f sublevel contains 7 orbitals.

for all elements, excluding hydrogen, there are 2 electrons in the first energy level. Hydrogen is the exception of this because it only has a single electron, thus it only has 1 in its first and only energy level.
