Updated: 11/3/2022

atomic number = number of proton in an element

number of proton = number of electron

mass number = number of proton + number of neutron

therefore...

atomic number = mass number - number of neutrons

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.

Is it possible for an element to have more than 1 atomic formula?

No, each element has a unique atomic formula based on the number of protons in its nucleus, which is called the atomic number. This atomic formula is represented by the element's chemical symbol.

What is the chemical formula for heluim?

The chemical formula for helium is He. It is a noble gas with an atomic number of 2.

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?

To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The formula is: Number of neutrons = Atomic mass - Atomic number

What is the atomic number for CH3?

The atomic number refers to the number of protons in an atom's nucleus. Since CH3 is a molecular formula representing a compound composed of carbon and hydrogen, it does not have an atomic number.
