Bonding of two or more atoms of same or different elements

Different version of same element containing different number of neutrons

Isotopes Explanation

All Isotopes of the element have same atomic number but different mass because of the difference in number of neutrons. Mass […]

One twelveth of the mass of an atom of carbon-12. It is equal to 1.66 x 10⁻²⁷ kg

Average relative mass of an atom of element compared to mass of carbon -12 taken as 12 a.m.u

The Avogadro’s law states that equal volume of all gases contains an equal number of molecules under similar conditions of temperature and pressure.

The law of combining volumes given by the Gay Lussac States that When gases react together, they bear a simple whole number ratio to one another and to the volume of products under same conditions of […]
