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
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
Carbon has four valence electrons, so it will need four more electrons 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.
