Electropositive element + Electronegative element = Ionic bond (electrovalent bond), Electronegative element + Electronegative element = Covalent bond, or less electro positive + Electronegative element = Covalent bond, Register and Get connected with IITian Chemistry faculty, Please choose a valid Shape of molecular orbitals depends on the number of valence electron on central atom. If the two atoms would have attracted each other instead of repelling, the energy of the molecule would have decreased and the molecule would have been                  stable. Inorganic chemistry takes less time during examination compared to numerical parts. Energy change on formation of a gaseous cation : To form a gaseous cation, an electron is removed from the neutral atom.

There are a total of 75 questions from all three subjects and for each subject, 100 marks are allotted. School Tie-up | Atoms may attain stable electronic configuration in three different ways by losing or gaining electrons by sharing electrons. As Lewis was unable to explain the shape of orbital, VSEPR theory was given by Sidgwick and Powell in 1940 and was later modified by Nyholm and Gillespie. The Valence Bond theory handles such species rather clumsily (odd-electron bonds etc.) About. Pay Now | Careers | Sitemap | It’s an easier way as well. 1.
