Consider a fluorine atom. It has 9 electrons, correct?
So, the first level of the electron shell can hold 2 electrons in one sublevel, 1s. The next level has two sublevels; 2s and 2p. It has 2 electrons in 2s, which is filled, and 5 electrons in 2p, which is unfilled. 2p can hold a maximum of 6 electrons, which fill the sublevel such that each orbital is filled sequentially until all three orbitals have one electron, and then all three orbitals have two electrons. Fluorine, because it does not have 6 2p electrons, has one unfilled orbital which has an unpaired electron.

Orbitals can contain up to 2 electrons but the 2 electrons must have opposite spin. So a unfilled orbital may have either zero (0) or one (1) electron in them. Filled orbitals are not capable of bonding as the quantum values are all 'employed'.

A filled orbital has the maximum amount of ellectrons it can have in it.And well the oppisite is an unfilled orbital.As Unfilled orbital has electrons in it, but not enough to fill it

Filled means what it says, the rings is filled with electrons, unfilled means it has vacancies.

Lust is completely actual - you elect to have intercourse with this man or woman, grope this man or woman. All physique stuff. Love is emotional - sure, there are factors of lust in love yet for the main section it incredibly is desirous to be with that man or woman, communicate with that man or woman, cuddle, and to stay with them invariably. tl;dr Lust leaves once you earnings some pounds, love remains and asks in case you desire cake.
