Molecular substances can only fill outer shells if there are enough electrons present for this phemena to occur. Electrons can also be taken from other molecular substances in a process known as a Reduction Reaction.
Sulfur has 6 electrons in its outer shell. Therefore, it needs 2 more electrons to fill its outer shell.
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
4 to fill the 2p 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).
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
The halogen family tends to gain one electron to fill their outer 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.
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.
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).
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.
