difference between average atomic mass and relative mass

An indirect method to determine the absolute mass of an atom has been devised. The mass of a particular atom is taken as a standard unit and the masses of other atoms are related to this standard. Hydrogen being the lightest elem..

A proton is actually a hydrogen atom, which has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is 1 a.m.u., the relative..

An atom or a molecule is a very minute particle; the actual mass of an atom is extremely small. The mass of atoms extends from 1.67 x 10 - 2 4 g (hydrogen) to 4.0 x 10 - 2 2 g only. It is physically not possible to measure such small and..

Relative Atomic Mass - An atom or a molecule is a very minute particle; the actual mass of an atom is extremely small. The mass of atoms extends from 1.67 x 10 - 2 4 g (hydrogen) to 4.0 x 10 - 2 2 g only. It is physical..

It is known that the atomic mass of an element/compound is not the mass of one atom or molecule of the said element/compound because they occur as a mixture of isotopes. As the atomic and molecular masses are expressed on a rela..

Relation Between Atomic Number and Atomic Mass - While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an el..

While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well...
