Chemistry Questions

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.

Semiconductors are those materials that are neither good conductors nor the good insulators of heat and electricity. Silicon (Si), Germanium (Ge) and Cadmium Sulphide (CdS) are semiconductors which work as conductors in some special conditions only.

Radioactive decay is likely to occur when the nuclei of an atom doesn't have enough binding energy to hold the nucleus together due to excess of rotons or nutrons in it.

The compound MgCl2 is named as Magnesium Chloride.

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

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