The atomic number tells how many protons are in the atom, and the Atomic Mass tells how many neutrons and protons are in the atom together.
Like Oxygen has an atomic number of 8. It also has 8 protons. It's atomic mass is 16. It also has 16 neutrons and protons. Helium's atomic number is 1. It only has 1 proton. It's atomic mass is 1 because it doesn't have any neutrons.
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
Calcium has atomic number of 20, an atomic weight of 40.078 and an mass numbers of 40 - 48 inclusive in its isotopes. Atomic number is the count of protons in the nucleus. Mass number is the count of protons plus neutrons. The question refers to atomic mass rather than atomic weight. Atomic mass normally refers to the mass of a specific isotope of an element and is related to the mass number. Atomic weight ( or relative atomic mass as it is termed by IUPAC) the average mass of naturally occurring isotopes of an element. The relationship between mass number and atomic mass is defined in terms of the Atomic mass unit which is in simple terms 1/12 of the mass of a 12C atom. If you need to find out more about the relationship between mass number and and atomic mass you need to read the article "atomic mass unit" in wikipedia.
The atomic weight of the element (syn.: mass number).
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.
atoms and atomic structure
The Atomic Mass number is the sum of the atomic number, the number of protons, and the number of neutrons in the nucleus of the atom.
it has 6 electons. atomic number is 6. Atomic Mass is 12.011
it has 6 electons. atomic number is 6. Atomic Mass is 12.011
Mendelevium has 101 protons and electrons. Number of neutrons = Atomic mass of an isotope - atomic number of mendelevium (101)
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.
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
The mass number is the total number of protons and neutrons in an atom's nucleus. The number of protons is the same as the element's atomic number, so the number of neutrons is the mass number minus the atomic number. The mass number can be determined by rounding the atomic weight to the nearest whole number. Also, the mass number is given as part of an isotope's name, for instance: Carbon-14 has a mass number of 14.
