How many neutrons does phosphorus -33 have?

Answer 1

18.

Phosphorus has an atomic number of 15, therefore it has 15 protons. Phosphorus-33 has a total of 33 protons and neutron and therefore has 18 neutrons.

Phosphorus-33 is a synthetic unstable isotope of P.

Answer 2

Ah, what a happy little question! Phosphorus-33 has 16 neutrons. Just imagine those neutrons snuggled up with the protons in the nucleus, creating a lovely balance in the atom. Remember, every element has its own unique number of protons and neutrons that make it special.

Answer 3

18 Neutrons.

Phosphorus-33 means it has a mass number of 33. Since Phosphorus has an atomic number of 15, it has 15 Protons. Since electrons almost have no mass, the only things contributing it are the Protons and Neutrons.

Take the method (Number of Neutrons = Mass Number - Atomic Number)

Number of Neutrons is Unknown, Mass number is 33 and the atomic number of Phosphorus is 15. Subtract 15 from 33 and you will end up with 18 Neutrons.

Phosphorus-33 is an isotope meaning it has more neutrons than the normal element. The normal Phosphorus has 16 Neutrons instead of 18.

Answer 4

33 protons

Atomic number = number of protons

Answer 5

Phosphorus-33 has 16 neutrons. This is determined by subtracting the atomic number (which is 15 for phosphorus) from the mass number (which is 33).

Answer 6

15 protons

18 neutrons.

Answer 7

33

Answer 8

69
