silicon's atomic number is 14 so, its electron configuration is 2.8.4, the third shell needs 4 more electrons to make it 8 and to become stable. ---> so the answer is 4.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
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.
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.
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
The halogen family tends to gain one electron to fill their outer shell.
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.
Carbon has four valence electrons, so it will need four more 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).
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.
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.
4 to fill the 2p shell
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.
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.
