How many electrons does phosphorus have in its penultimate shell?

If "penultimate" means "next-to-outermost", the correct answer is 8: The innermost shell is full with two 1s electrons; the next-to-outermost shell is full with two 2s electrons and six 2p electrons, for a total of 8. The outermost shell has five valence electrons, constituting with the two inner shells the remainder of the proper number of total electrons for phosphorus, 15, its atomic number.


How many possible electrons are found in the second shell?

8 electrons can be accommodated in the 2nd shell (aka 2nd energy level). 2 in the 2s orbital and 6 in the 2p orbitals.

How many electrons are in the valence shell of He?

There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.


How many valence electrons need to be accommodated in the Lewis structure for OF2?

6 valence electrons need to be accommodated in the Lewis structure for OF2. This accounts for the oxygen atom's 6 valence electrons and the fluorine atom's 1 valence electron each.


How many electrons can you fit on each energy level?

The maximum number of electrons that can be accommodated on each energy level is given by 2n^2, where n is the principle quantum number of the energy level. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
