The phosphorus atom has 15 protons and electrons and 16 neutrons.
Phosporus is a p block element too. AN ATOM HAS 15PROTONS AND NEUTRONS.
P is a p block non metal. Atom contains 15 protons.

Phosphorus (P) has 15 protons and 15 electrons. Phosphorus-31, the only stable isotope of Phosphorus, has 16 neutrons.
Well... the element number defines the number of protons, and usually the electrons. the neutrons are determined with... i dunno :P I.E. hydrogen is 1. Therefor, in hydrogen there are 1 protons and 1 electrons.
Protons - 108 Neutrons - 169 Electrons - 108 I think. :P
PHOSPHORUS (P): Protons: 15 Electrons: 15 Neutrons: 16
Protons and Electrons= 15 Neutrons=16 *The isotope 31P is the only naturally occurring form of phosphorus. Forms with 17 or 18 neutrons have been synthesized, and are unstable radioisotopes.
There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.
Electrons~ 11 Neutrons~11 12Protons~11Youre welcome(;___________________________ (Improved answer) No, It has 11 electrons, 11 protons and 12 neutrons.

There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.
Without knowing which nuclide is in question, it remains safe to say that regardless of the element, in an ion the atomic number or count of protons differs from the number of electrons - and thus the atom is overall not electrically neutral - the definition of an ion. With fewer electrons than protons, it would be a positively charged ion (cation); with more electrons than protons, it would be a negative ion (anion). If the atomic number (proton number) is P, the charge is x and the mass number is M, then protons = P neutrons = M- P and electrons is the algebraic sum of P and x.
