How do you write a mathematical formula for figuring out the number of neutrons in an atom if you know the atomic number and the atomic mass?

It's quite simple. It's just the Atomic Mass minus the atomic number. That's because the atomic number is simply the number of protons and the atomic mass is (almost exactly) the number of protons plus neutrons. Unfortunately there is a complication.
The problem is that a particular element can have more than one isotope.
Each isotope has the same number of protons, but different numbers of neutrons. This can make the atomic mass a messy number that's not a nice whole number.

What does the formula atomic mass minus the atomic number equal?
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.

Can you identify an atom without knowing number of neutrons in it?
Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
No. of neutrons=Atomic mass -Atomic No.=10-3=7 It has 7 neutrons.
What does atomic mass do?
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
What is the formula to get a number atomic neutron?
No. of neutrons=Atomic mass - Atomic number
How many neutrons are in selenium-76?
A simply formula is the atomic mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.
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

The formula of neutron?
If you mean to find the amount of neutrons in an atom, you take the atomic mass and subtract the atomic number (the number of protons). That gives you the average number of neutrons.

Atomic number of 2 and atomic mass of 4 how many neutrons?
To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
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.
