atomic mass- (chemistry) the mass of an atom of a chemical element expressed in atomic mass units atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an ...
A unit for atomic mass has been devised for dealing with the mass of individual atoms and molecules that is based on the carbon atom for chemistry. An atomic mass unit is 1/12 of the mass of a carbon-12 isotope. To seven significant digits, a 1.000 000 atomic mass unit is equal to ...
The atomic number of an atom is always equal to the number of protons that are found in that atom. This number can typically be found on a periodic table above the symbol in an element's box. The number of protons in an atom is similar to the DNA of a human; it is responsible ...
