The valency of an element is _____ (a) the combining capacity of one atom of it (b) the number of bonds formed by its one atom (c) the number of hydrogen atoms that combine with one atom of it (d) all the above Answer. Chemical Bonding Vy Bui, Lalein A. Pajarillo 2. The molecule settles in a state where the Electron Pairs are furthest apart from each other. Through chemical bonding Class 11 notes, it becomes easy for the students to know all the essential things that are present in the chapter. Electrons occupy the shell closest to the nucleus which can hold only 2 electrons and which go in separately. This is a structure composed of ‘sheets’ of carbon atoms on top of each other. They are held together in these compounds by chemical bonds. Metals do not tend to dissolve, except in liquid metals, due to the strength of the attraction between the metal ions and the electrons. Mainly that atoms bond due to attractions and to become more stable by transferring or sharing electrons. IntroductionChemical Bond – the type of force that holds two or more atoms together. 1.
