The mass number is found directly beneath the Element Symbol.
Hint: Hydrogen (H) has a mass of 1.00794
Each cube should look similar to this:

To find the mass number of an atom, you add together the number of protons and neutrons in the nucleus of the atom. The atomic mass listed in the periodic table is the weighted average of the mass numbers of all isotopes of that element.
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
Find out how many protons (atomic number) and what the mass number of a particular element is. Then subtract the number of protons from the rounded mass number to get the number of neutrons in a particular atom.
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.
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 mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.
Proton + Nuetron = Atomic Mass
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.
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 of an atom is the combined mass of the protons and neutrons in the nucleus.
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.
