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 element and be..

Atomic Number and Atomic Mass - The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the n..

The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal to the ..

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..

Atom was derived from the Greek word 'atoms', meaning 'indivisible'. Thus, it was considered to be indivisible.Atoms of the same element are identical in shape, size, mass and other properties.Atoms cannot be created, divided or destroyed duri..

In 1967, the atomic clock was adopted, choosing caesium-133 atom, which emits electromagnetic radiation of a precise and unvarying frequency, corresponding to the transition between two hyperfine levels of the ground stat..

Mass - The SI unit is kilogram. 1 kg is defined as the mass of a platinum-iridium cylinder kept at the International Bureau of W and M at Sevres, France, established in 1887. The atomic structure of mass is yet to be develop..
