15 protons is a dead giveaway that we're dealing with phosphorus (it is atomic number 15). 18 electrons means it has 3 extra (18-15 = 3) electrons, each electron has a -1 charge, so we have 3 extra -1 charges...
So putting it all together we get: P3-
An ion with 15 protons and 18 electrons has a net charge of +3 since it has 3 more electrons than protons. This ion would be classified as a cation.
P3- has 15 protons, 16 neutrons and 18 electrons.
The charge of an atom is determined by the number of protons and electrons it has. In this case, the atom would have an overall charge of +15 since it has 15 protons and 100 electrons, resulting in a net positive charge of 15.
'-3' It is not an atom, when it is a charged species, but an ION. 15 protons (15+) 18 electrons (18-) Hence +15 - 18 = -3 The charge. By the numbers given , this is the element Phosphorus. , which can exhibit a 'P^(-3) ion.
the nucleus always has a positive charge. The atom on the other hand in its singular state will have no charge as the electrons negative charge counter the protons positive charge. in this example there will be 31 electrons The element would be Gallium but there are not enough neutrons in your question to even make a viable isotope. Gallium typically has 31 protons and 39 neutrons

P3- has 15 protons, 16 neutrons and 18 electrons.
The electrical charge is +3; this is the isotope aluminium-28.

15 Electrons. A charge-less (neutral) atom must have an equal number of both protons and electrons, otherwise it becomes an ion.
'-3' It is not an atom, when it is a charged species, but an ION. 15 protons (15+) 18 electrons (18-) Hence +15 - 18 = -3 The charge. By the numbers given , this is the element Phosphorus. , which can exhibit a 'P^(-3) ion.
This ion would be an atom of phosphorus with a +3 charge, as phosphorus typically has 15 electrons and 15 protons (which gives it a neutral charge). The number of neutrons doesn't affect the charge of the ion, so it would still be considered a phosphorus ion with a +3 charge.

That particular atom will have a positive two (+2) charge. Charged atoms are more commonly known as ions.
The phosphide ion has 18 electrons as it forms an anion with the valency of three.
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
Phosphorus' atomic number is 15. Thus it has 15 protons, all of which have a +1 charge. To balance out the charge, it also must have 15 electrons.
