Group #15 has 5 valence electrons
5
The last letter represents how many valence electrons are. So:
K: 2e
L: 8e
M: 5e
The valence of the element is 3 (8-no. of valence electrons). Note that that formula is correct for nonmetals only. The element is P and has the electronic configuration [Ne]3s2 3p3 or 1s2 2s2 2p6 3s2 3p3. It has to gain 3e to get from 3p3 to 3p6.
Group 1 elements have 1 valence electron, group 2has two valence electrons and group 15 has 5 valence electrons.
as it belongs to group 5 so valence electrons are 5.
ex-> nitrogen
15-10=5

If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
Phosphorus (neutral atom) has 15 electrons.
A neutral phosphorus atom has 15 electrons.
15 protons, 15 electrons and 16 neutrons (for its most stable isotope)
A molecule of nitric oxide has 15 electrons overall, 7 from the nitrogen atom and 8 from oxygen.
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
15 electrons
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
phosphorus have 15 electron because you know the atomic number to know electron
The neutral atom of phosphorus has 15 electrons in the atom.
A phosphorus atom has 15 electrons.
