However, in covalent bonds, the valence electrons from both of the two atoms are shared between two atoms. Thus, neither atom is given a full positive or negative charge. Instead, the electrons shared between the two atoms-whether it be 2, 4, or 6 electrons-varies from molecule to molecule.There are two types of covalent bonds: pure covalent bonds and polar covalent bonds.ach covalent bond consists of two electrons, one usually from each atom involved in the bond. The atoms form enough covalent bonds that when the electrons in the bonds are added with the valence electrons, they will have an octet.
Lakh is a term in the Indian numbering system. 1 lakh = 100 thousand. The term is also used widely in other parts of South Asia-Pakistan, Nepal, Bhutan, Bangladesh, Sri Lanka and Maldives.
The term lacquer originates from the Sanskrit word lÄksh Ä' (à¤²à¤¾à¤à¥à¤·à¤¾) meaning wax, which was used for both the Lac insect (because of their enormous number) and the scarlet resinous secretion it produces that was used as wood finish in ancient India and neighbouring areas.aw lacquer can be coloured by the addition of small amounts of iron oxides, giving red or black depending on the oxide. There is some evidence that its use is even older than 8,000 years from archaeological digs in China.
