Group #15 has 5 valence electrons
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
An atom of phosphorus typically has 15 electrons.
A neutral phosphorus atom has 15 electrons.
You should understand that while neutral atoms have the same number of protons and electrons, they do not usually have the same number of protons and valance electrons, because except for hydrogen and helium, atoms also have electrons in the inner shells, which are not valance electrons. Therefore, there is no atom which has 7 protons and 7 valance electrons, although there is an element that has 7 protons, and there are several elements that have 7 valence electrons.
Phosphorus (neutral atom) has 15 electrons.
there are 5 valence electrons in a Phosphorus element!
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
15 electrons
An atom of phosphorus typically has 15 electrons.
The neutral atom of phosphorus has 15 electrons in the atom.
A phosphorus atom has 15 electrons.
A neutral phosphorus atom has 15 electrons.
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

An atom of antimony has 5 outer shell electrons. Antimony is in group 15 of the periodic table, so it has 5 valence electrons.
