Phosphorous-32 has 17 neutrons in its nucleus.
You can work it out like this :-
The atomic number for Phosphorous is 15 (that means it has 15 protons and 15 electrons). The + charged protons sit in the nucleus and are electrically balanced by the - charged electrons that orbit the nucleus.
If you subtract the atomic number (15) from the atomic weight (32) this tells you how many neutrons there are accompanying the protons in the nucleus because the electrons essentially weigh nothing.
how many neutrons there are in a phosphorus atom? The normal isotope of phosphorus is P - 31, which has 15 protons and 16 neutrons. Unstable isotopes are P-32 and P-33 which have 17 and 18 neutrons respectively.
Phosphorus-32 (P-32) has 16 neutrons. This is determined by subtracting the atomic number, which is 15 for phosphorus, from the atomic mass, which is 32 for phosphorus-32.
Germanium has 32 protons, so for an isotope with atomic number of 70, it will have 70 - 32 = 38 neutrons in its nucleus.
27 protons, 32 neutrons, 0 electrons.There are no electrons in the nucleus, they are in the orbitals surrounding the nucleus.
Phosphorus-31 contains 16 neutrons, 15 protons and it is Stable
Phosphorus-32 (P-32) has 15 protons, as all phosphorus atoms do. It has 17 neutrons, which is derived from its mass number of 32 (32 - 15 = 17). Additionally, in its neutral state, P-32 has 15 electrons, equal to the number of protons.
Have different atomic mass (have different numbers of neutrons)
32
The isotope (^{32}\text{P}) (phosphorus-32) has 15 protons, as phosphorus has an atomic number of 15. The mass number is 32, so it has (32 - 15 = 17) neutrons. The (3-) charge indicates it has gained three electrons, giving it a total of (15 + 3 = 18) electrons. Therefore, (^{32}\text{P}^{3-}) has 15 protons, 18 electrons, and 17 neutrons.
The isotope with 15 protons and 17 neutrons is Phosphorus-32, which has a symbol of P-32.
They both have 15 protons and an atomic number of 15. They also both have a 0 charge and 15 electrons in their atom. The main difference between them is that P-31 has 16 neutrons in the nucleus whereas p-32 has 17.
To identify the element, we subtract the number of neutrons (17) from the atomic mass (32). This gives us the number of protons, which is 15. The element with 15 protons is phosphorus, so the isotope in question is phosphorus-32.
