In Argon, Potassium and Calcium, the limit is eight, but because of the overlapping energy levels, In everything from Scandium upwards, the limit is eighteen.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Antimony needs 3 electrons to fill its valence shell, which has 5 electron slots. Antimony typically forms compounds by gaining 3 electrons to achieve a stable octet configuration.
An atom of nitrogen has 5 electrons in its outer shell. This makes nitrogen a nonmetal and means it requires 3 more electrons to fill its outer shell and become stable.
Nitrogen has two energy levels. The first energy level contains two electrons. The second energy level contains five electrons. Number of Protons/Electrons: 7 Number of Neutrons: 7
Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Nitrogen needs 3 more electrons to fill its outer shell. It has 5 electrons in its outer shell, and it typically needs a total of 8 electrons to achieve a full outer shell (octet rule).
Antimony needs 3 electrons to fill its valence shell, which has 5 electron slots. Antimony typically forms compounds by gaining 3 electrons to achieve a stable octet configuration.
An atom of nitrogen has 5 electrons in its outer shell. This makes nitrogen a nonmetal and means it requires 3 more electrons to fill its outer shell and become stable.

Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
thallium has 3 electrons in outermost shell.
Phosphorus has 5 electrons in its valence shell. To fill the valence shell, it needs to gain 3 more electrons, bringing the total to 8 electrons, which is a stable configuration known as the octet rule.
The first electron shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 18 electrons. Therefore, a total of 28 electrons are needed to fill the first three electron shells.
Boron has three electrons in its outer shell
As Nitrogen (N) have atomic number 7, and electronic configuration is 2,5. therefore N required 3 elecrons to complete their outermost shell or orbital.
