The atomic number gives you a hint of how many protons are in the atom. While mass is the weight of the whole atom( including protons, electrons, and neutrons).
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
The atomic mass unit is used to express the measure of the atomic mass.
mass number=atomic number+no. of neutrons
It is equal to the difference between atomic number and Atomic Mass number. A+
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.
Iodine is 127 and Magnesium is 24 so the difference is 103 atomic mass units.
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
The mass number is the number of the Atomic Mass. The atomic mass is the mass of the atom of the element. There is no difference between the two, except mass number is referring to the number, while atomic mass is referring to the atom's mass in general, which is also expressed by a number. Basically, both terms mean the exact same thing.
Atomic Mass is the mass of an atom in Atomic Mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
Atomic Mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the 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.
