The number of electrons depends on the element and it may vary from 1 to 2 (for s block elements), 3 to 8 (for p block elements), 1 to 10 for d block elements and 1 to 14 (fro f block elements).
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
4 to fill the 2p shell
Carbon needs 4 electrons to fill up its outer shell. It has 4 valence electrons and can achieve a full octet by gaining 4 more electrons.
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).
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
8
There is a total of 8 electrons that are needed to fill outer shell of most atoms. An atom is the smallest unit of matter.
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.
