How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?

It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.


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


If an atom has an atomic namber of 20 and a mass namber of 53 how many protons and neutrons does that atom have?

uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.


Boron has an atomic mass of 11 and an atomic number of 5 how many neutrons must there be?

The mass of an atom is found by adding the number of the protons and neutrons. So, a boron atom with 5 protons and 6 neutrons would have an atomic mass of 11.


How many neutrons does a cesium 141 have?

The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
