∙ 13y agoA Phosphorus atom has 15 electrons.
Every Element on the Periodic Table has an atomic number, it is usually shown in the top center of the box for the element. and they go in sequence from lowest to highest. Hydrogen 1, Helium 2, etc...
The atomic number is a measure of how many protons an atom has. In order to be an atom, and not an ion, the element must have a neutral charge ... i.e. the same number of electrons as protons.
1. So by definition: an atom must be neutral
2. If the atom is neutral, then it must have the same number of protons and electrons
3. If Phosphorus has 15 protons (It's atomic number is fifteen) then it also has 15 electrons.
