the number of protons and neutrons,
The average weight in grams of one mole of the element.
If you mean "how does one determine an atoms atomic mass?", then the answer would be to find a periodic table of elements where the whole numbers indicate atomic number and the other indicating atomic mass. Atomic number is generally described as the number of protons in a naturally occurring atom of a given element, and the atomic mass is the number of protons + number of neutrons in an atom.
No. Everything has mass. Atoms have mass, Everything has atoms. :) Atomic Mass Number for example. :)
The atomic number refers to the number of protons in an element. The mass number can be used to indicate the number of neutrons because both protons and neutrons have a mass of about 1. An oxygen atom has 8 protons and 8 neutrons.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The atomic mass unit is used to express the measure of the atomic mass.
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Cobalt is an atomic mass of 58.93 atomic mass units
Atomic no.=no. of protons Atomic Mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass of magnesium is approximately 24.305 atomic mass units (amu).
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
