How many neutrons does a phosphorus-32 atom have?

Answer 1

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.

Answer 2

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.

Answer 3

The number of protons in a compound is equal to its atomic number. Therefore, all phosphorus atoms have 15 protons. The number of neutrons is equal to the Atomic Mass minus the number of protons, and therefore is 17.

Answer 4

A phosphorus-32 atom has 15 protons and 17 neutrons.

Answer 5

Neutrons has 17

all you have to do is minus phosphorus 32 and 15 which is atomic number and neutrons is 17.

Answer 6

Phosphorous, atom number 15, has 15 protons and (32-15=) 17 neutrons in the nucleus of isotope P-32.

Answer 7

P-32, atom number 15, has (32-15 =) 17 neutrons in nucleus.

Answer 8

Protons: 15

Neutrons: 16

Electrons: 12

Answer 9

Mass number = 32

Atomic number = 15

Mass number - atomic number = number of neutrons

32 - 15 = 17 neutrons

Answer 10

15protons and 17 neutrons
