Mass number = no. of protons + neutrons Atomic number = no. of protons


Thus (mass number - atomic number) gives you no. of neutrons.


Therefore for phosphorus, the number of neutrons would be 16.

If Phosphorous has an atomic mass of 30 and atomic number of 15 how many neutrons does it have?

Atomic mass is equal to the number of protons + neutrons present in the nuclide. The atomic number is defined as the number of protons in the nuclide. Therefore to find the number of neutrons use the formula: atomic mass = #protons + # neutrons solving for # of neutrons you get: # neutrons = atomic mass - # protons plug in the given values: #neutrons = 31 - 15 # neutrons = 16


How many neutrons in atom Phosphorus 31?

Since the atomic number of Phosphorus is 15, an atom of Phosphorus-31 would have 16 neutrons. This is calculated by subtracting the atomic number (15) from the atomic mass (31).


Which element has 30 neutrons and 15 electrons?

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.


How many neutrons does p32 have?

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.


How many neutrons does phosphorus -33 have?

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.


What is the approximate atomic mass of a nuclide of phosphorus that an atomic number of 15 and that has 16 neutrons?

The atomic mass of phosphorous-31 is 30,97376163(20).


How many neutrons are there in an atom of 32p?

Phosphorus-31 contains 16 neutrons, 15 protons and it is Stable


Why is 40 the mass number of phosphorus?

Phosphorus is a non metal element. Mass number of it is 31.


What has 16 neutrons in the nitrogen family?

Phosphorus, as a member of the nitrogen family, has 16 neutrons. The atomic number of phosphorus is 15, meaning it has 15 protons in its nucleus. With 16 neutrons, the total mass number of phosphorus is usually 31.


If phosphorus had 16 neutrons what would change?

Not much. Phosphorus, atomic number 15, has an average atomic weight of about 31, indicating that most phosphorus atoms already have 16 neutrons.


How many protons electrons and nue trons does Phosphorus have?

The most stable isotope of phosphorus is phosphorus-31. The atomic number of phosphorus is 15, so it has 15 protons. In a neutral atom, there will also be 15 electrons. The number of neutrons is mass number minus atomic number, which is 31-15, so the number of neutrons is 16.


What is the number of neutrons in phosphorus-31?

the number of neutrons is mass
