it very easy: whatever row the element is in is the number of energy levels it has. Example: hydrogen in the first row, it has 1 energy level.

Electrons in the highest occupied energy level of an atom are the valence electrons.
The electrons in the outer-most shell are known as valence electrons.
Polonium-210, with an energy output of 5.307 mega-electronvolts (MeV) per atom.
In the Valence shell... which is the outermost energy level.
The highest occupied energy level in an atom is often called the valence shell.
valence electrons can be determined

The period tells you how many energy levels an atom has.
It has 2 unpaired electrons and 8 empty electron levels.
You shouldn't use terms like "outer level", because they're confusing. It could potentially mean at least two things, specified more precisely below. The highest occupied energy level of a ground state neutral carbon atom, the 2p level, has two electrons. The number of electrons in a ground state neutral carbon atom that have a principal quantum number of 2 (the highest associated with any electrons in such an atom) is four.
the period number tells which is the highest energy level occupied by the electrons

There are two electrons.

The period tells you how many energy levels an atom has.
When the highest occupied energy level of an atom is filled with electrons, the atom is stable and not likely to react.
3p is the highest "occupied" orbital of an "unexcited" neutral Silicon atom.
Electrons...MoMMy =)
