The Atomic Mass NUMBER equals the number of protons and neutrons in an atom.
DO NOT confuse this with the mass of an atom.
Atomic number = number of protons = number of electrons = number in the Periodic Table Atomic mass is the mass of an isotope or an element.
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

The atomic mass number of iodine is 17.8923
Atomic number 6, atomic mass 12.
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.
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
atomic number
the protrons, neutrons and electrons in a atom
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
Atomic number: number of protons or electrons in a neutral atomMass number: sum of protons and neutrons in the atomic nucleusAtomic mass number is not a very correct expression.
The isotope symbol for the element with atomic number Z=28 and mass number A=64 is ^64Ni.
Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
The combined number of protons and neutrons is known as the mass number of an atom. It can be used to calculate the atomic mass by adding the total number of protons and neutrons in the nucleus of an atom.

We can find calcium as a non metal element. Atomic number of it is 20.
