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.
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.
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
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
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 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).
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.
Yes. Two of the electrons will go into the carbon's outer s shell (2s) to completely fill it (s orbitals can contain up to two electrons) and the remaining two will go into its outer p shell (2p).
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
4 to fill the 2p 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.
