One electron is needed.
Sulfur has 6 electrons in its outer shell. Therefore, it needs 2 more electrons to fill its outer shell.
In case of sulphur there are 3 energy levels.The first one contains 2 electrons,the second one contains 8 electrons and the third one contains 6 electrons.So the atomic number is 16 and valence electron/number of electrons in the outermost shell is 6.
The atomic number for nitrogen is 7. Neutral nitrogen must have both 7 electrons and 7 protons then. The first 7 orbitals are filled as 1s2 2s2 2p3, which shows us that nitrogen has 5 valence electrons.
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
Nitrogen has 5 valence electrons. Valence electrons are the electrons that are found in the outer most shell of an atom, and are consequently the electrons that move from atom to atom in the formation of compounds. The reason for this is a result of the electron configuration. A nitrogen atom has 3 orbitals; the 1s orbital, the 2s orbital, and the 2p orbital. In this case, the 2s and 2p orbitals are the valence orbitals, as they have the electrons with the most energy. With 7 protons, a neutral nitrogen atom has 7 electrons. The s orbitals can only hold 2 electrons, and the p orbitals can hold up to 6 electrons. The 1s orbital is filled first, leaving five electrons, then the 2s orbital is filled, leaving 3 electrons, and then these remaining electrons fill the 2p orbital halfway. There are a total of 5 electrons in the 2s and 2p orbitals, and since these orbitals have the most energy, there are 5 valence electrons.
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 requires 3 electrons to fill its outer shell. This allows it to achieve a stable configuration similar to a noble gas.
Nitrogen has 5 electrons in its outer shell. In order to fill the outer shell, it needs a total of 8 electrons.
Nitrogen needs 3 electrons to fill its outer shell. It has 5 electrons in its outer shell and 2 of them is already filled in, so it requires 3 more electrons to complete the outer shell with a total of 8 electrons for stability.
Sulfur has 6 electrons in its outer shell. Therefore, it needs 2 more electrons to fill its outer shell.
Carbon has 4 electrons in its outer shell. To fill its outer shell, carbon needs 4 more electrons to achieve a full valence shell of 8 electrons.
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Outer electrons, or Valence Electrons, for nitrogen is 5 electrons. The first electron level requires 2 electrons, an electron pair, to fill it and move on to the next level. Nitrogen has 7 electrons, so 7-2=5.
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).
4 to fill the 2p shell
In nitrogen, the inner shell consists of two electrons, which fill the 1s orbital.
