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 else can I help you with?
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.
When figuring atomic mass the mass of is ignored?
When calculating atomic mass, the mass of electrons is typically ignored because it is so small compared to the mass of protons and neutrons. Electrons have a much smaller mass relative to protons and neutrons, so they do not significantly contribute to the total atomic mass of an atom.
What is the mathematical formula for an atomic bomb?
The mathematical formula for the energy produced by an atomic bomb is E=mc^2, where E is energy, m is mass, and c is the speed of light. This formula, derived by Albert Einstein, explains the conversion of mass into energy in nuclear reactions, such as those that occur in atomic bombs.
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
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
What is the formula to get a number atomic neutron?
No. of neutrons=Atomic mass - Atomic 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.
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 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.
What is the Formula to calculate number of nuetrons in a nuclide?
The number of neutrons in a nuclide can be calculated using the formula: [ \text{Number of Neutrons} = \text{Mass Number} - \text{Atomic Number} ] Here, the mass number is the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Thus, subtracting the atomic number from the mass number gives the number of neutrons.
What is the formula for finding the amount of neutrons in an element?
The formula for finding the amount of neutrons in an element is: Number of neutrons = Atomic mass number - Atomic number. The atomic mass number represents the sum of protons and neutrons in the nucleus of an atom, while the atomic number represents the number of protons. Subtracting the atomic number from the atomic mass number gives you the number of neutrons.
When figuring atomic mass the mass of is ignored?
When calculating atomic mass, the mass of electrons is typically ignored because it is so small compared to the mass of protons and neutrons. Electrons have a much smaller mass relative to protons and neutrons, so they do not significantly contribute to the total atomic mass of an atom.

How can you calculate the number of neutrons N in an atom?
equal to number of protons
The formula of neutron?
The formula for a neutron is n. Neutrons are subatomic particles with no electrical charge and a mass slightly greater than that of a proton. They are found in the nucleus of an atom.
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
