The Atomic Mass NUMBER equals the number of protons and neutrons in an atom.
DO NOT confuse this with the mass of an atom.
The atom's mass number is the amount of protons and neutrons in the atom's nucleus.
A(mass #) = Z(Atomic #) + N(# of neutrons)
Mass number = number of protons + number of neutrons.
Atomic number = number of protons = number of electrons = number in the Periodic Table Atomic mass is the mass of an isotope or an element.
Atomic number = Number of protons = Number of electrons
protons and electrons it has
Grams per mol of 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.
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
A hydrogen atom has one proton, one electron and '''zero''' neutrons. Rephrased, the question is: Hydrogen's number of neutrons equals mass number - atomic number.
Number protons + number neutrons is called the mass number or the atomic mass.
The atomic number is the number of Protons The mass number is the number of Protons and Neutrons The number of Electrons always equals the number of Protons Therefore according to the above information the atomic number of the atom is 5 HOWEVER there is NO element with a mass number (atomic mass) of 9 with an atomic number of 5. You question is impossible to answer. Beryllium has an Atomic mass of 9.0122 and an Atomic number of 4 Boron has an Atomic mass of 10.811 and an Atomic number of 5
Number of protons = atomic number = 6 atomic units Number of protons + neutrons = mass number = 13 atomic units
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.
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)
Mass number is the sum of neutrons and protons. It is equals to total of their weights. As an example hidrogen-2 (deuterium) has a mass number of 2.
