### How to determine the number of neutrons an atom contains if you know its mass number and atomic number?

If you know the atomic number and the mass number, you can simply determine the number of neutrons using this formula: Mass number = (number of protons) + (number of neutrons) Or, Number of neutrons = (mass number) - (number of protons) All you have to remember is that the atomic number is the number of protons an atom contains.

### How to find the number of protons atomic number and the mass number with 12 as the number of electrons and 10 as the number of neutrons?

Natural atoms are electrically neutral and their proton number equals their electron number. The atomic number is the number of protons. The mass number is the number of protons and neutrons.

### How do you find out the number of electrons from atomic number and mass number?

* The number of electrons is equivalent to the number of protons. (unless it is an electrically unbalanced ion) * The atomic number is the number of protons in an atom, therefore, the atomic number is the number of electrons. * Mass number - number of neutrons = Number of protons = Number of electrons * Number of neutrons = Atomic mass - Number of protons (Mass number - Number of protons = Number of… Read More

### What are the number of protons neutrons and electrons in an element?

Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons

### How do you calculate a mass number?

Mass number is the sum of the number of protons and the number of neutrons in the atom: Mass Number = Atomic Number + Number of Neutrons.

### How do you determine number of subatomic particles for a element?

Number of protons = Number of electrons = Atomic number Number of neutrons = Mass number - Number of protons

### Would you use atomic number or mass number or both to obtain the number of particles in an atom?

atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.

### Do protons and electrons have the same number as the mass number?

No. The number of protons plus the number of neutrons is the mass number. The number of protons, which is also the number of electrons, gives the atomic number.
