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.
5: The other two of the total of 7 electrons in a nitrogen atom are in the inner shell.

there are two shells of electrons in the nitrogen atom that actually have electrons in them, nitrogen has two electrons in the first shell, the S orbital, and five in the outer shell, the P orbital. this causes nitrogen to have a valence shell with five electrons.
There are 2 electrons in the valence orbital of a Magnesium atom.
1 in the 4s orbital, 19 electrons in all (K has an atomic number of 19)
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
One electron is needed.
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.

Valence electrons are electrons found in the outer orbital (shell of an atom) They are the electrons used for bonding
Xenon is found in group 18. It has an electronic configuration of 2, 8, 18, 18, 8 and has eight valence electrons (or eight electrons in the outer most orbital).
No. Valence electrons are the electrons in the outer most orbit (or energy level) and not in outer most orbital.
Seven (7)
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
These electrons are called "outershell electrons" or "valence electrons."
