Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.
The number of electrons is 18.
It has a negative charge; to be more specific it has a charge of -3, since it has only 5 valence electrons and it would like to gain 3 more to be stable at 8.
Since electrons are negative, they get a negative charge.
A charge which is not a positive charge is a negative charge.
Electrons have a negative charge. Protons have a positive charge, and neutrons have a neutral charge. Added: Electrons always have a negative charge, value: minus 1.602*10-19 Coulomb.
No. Electrons possess a negative charge, therefore an atom with an excess of electrons will have an overall negative charge.
Electrons charge is a negative
negative
They do have a charge, it's negative
only the electrons have a negative charge but they go around the nucleus
Electrons have an electrical negative charge.
Pprotons have a positive charge neutrons have no charge and electrons have a negative charge. However the one with the smallest mass is electrons.
It has a negative charge; to be more specific it has a charge of -3, since it has only 5 valence electrons and it would like to gain 3 more to be stable at 8.
Electrons have a negative charge.
Electrons have a negative charge.
Electrons have a negative charge.
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
Since electrons are negative, they get a negative charge.
