16 neutrons in the most stable isotope of phosphorus (15P31).
An atom with 15 protons is an atom of phosphorus (P).
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
An atom is larger than a neutron; a neutron is a part of any atom except a hydrogen atom.

A Neutron - The nucleus of an atom consists of a number of protons and neutrons - with electrons 'orbiting' the nucleus like tiny planets.
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps
There is no 'neutron atom'. If you mean 'neutral' atom, then the answer is yes.
No, whenever an atom emits a positron its atomic number is decreases by one unit (because a proton is converted into a neutron and a positron) but atomic mass remains the same so phosphorus is converted into silicon atom with same atomic mass.
An atom with 15 protons is an atom of phosphorus (P).
The atomic number of phosphorus is 15. So there are 15 protons and 15 electrons in phosphorus.
All phosphorus atoms have 15 protons (hence their atomic number of fifteen). Assuming the atom is neutral, it will also have an equal amount of electrons.

Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
The atomic number of phosphorus is 15. So there are 15 protons
mass number= no. of protons + no. of neutron
Of course, number of neutrons or neutron number !
In a neutral atom the protons and neutrons are equal; protons are determined by the element's atomic number. Therefore, the "neutron number" can refer to the atomic number- in a neutral atom only.
