Deuterium, which is an isotope of hydrogen, has an Atomic Mass of 3. It has one proton and two neutrons in its nucleus.
This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
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.
Atomic mass
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.

Proton + Nuetron = Atomic Mass
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
Atomic mass
The number of neutrons in an atom can affect the atomic mass of an atom.
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
The Atomic Mass of one (1) atom of sulfur is 37.02. The atomic mass of three (3) atoms of sulfur is 96.21. 32.07 * 3 = 96.21
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)
Mass of C-12 atom = 12 amu mass of C-12 atom = am So atomic mass of A = 4 amu source ; www.examville.com
The atomic mass of an atom is the mass of 6.011 X 10^23 atoms of that element.
