Isotopes are atoms of the same element that have different mass numbers.

Example : Hydrogen, Deutirium and tritium all these have different mass but same atomic numbers.

German Chemist, Adolf von Baeyer first synthesized Barbituric Acid in 1864.

A chemical bond in which the electrons are not shared equally due to differences in the electronegativity of the atoms.

The polarity of a covalent bond is measured using its dipole moment.

 Large dipole moment = more polar

 Small dipole moment = more nonpolar.

An ionic bond is formed between two molecules when transfer of valency electrons take place between them. 

The first two steps in the lithification process are Compaction and Cementation.
