Is atomic mass number of protons or number of electrons if a neutral atom?

Neither, except for the anomalous hydrogen-1 isotope. The atomic mass number of an atom is the sum of the numbers of protons and neutrons in the atom. If the questioner meant "atomic number" instead of "atomic mass number", the atomic number is fundamentally the number of protons, but if the atoms is neutral, the numbers of protons and electrons are the same.

Is it true that The atomic mass is equal to the atomic number?

No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.

How do you know the number of neutrons an atom has?

You can find the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass number (rounded atomic weight). The atomic mass number represents the sum of protons and neutrons in the nucleus.


Difference between atomic and mass number?

Atomic number shows the number of protons in an element and the mass number shows the number of protons+neutrons In an electrically neutral atom, atomic number is also the number of electrons .
