8 electrons present in 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.
we know that 1st shell contain 2 electrons 2nd shell 8 electrons but third shell have to contains 18 electrons but the maximum no. of electrons that can be accommodated in the outermost orbit is 8 electrons...... by yhell
Four valence electrons need to be accommodated in the Lewis structure for F2. Each fluorine atom contributes seven valence electrons, totaling to fourteen valence electrons in the molecule.
1st shell: 2 electrons, 2nd shell: 8 electrons, 3rd shell: 8 electrons, 4th shell: 4 electrons, 5th shell: 0 electrons, 6th shell: 0 electrons.
Sulphur has 6 electrons in its outermost 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.

It has 5 electrons in its outermost shell.
there are two electrons the first shell hold
Sulphur has 6 electrons in its outermost shell.
There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.
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.
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.
