Particles that collide with insufficient energy have unsuccessful collisions and just bounce off each other. The rate of a reaction is therefore also dependent on the energy of collisions as well as the number of collisions. To increase the rate of a reaction then the number of successful collisions needs to be increased. The right answer is C. Covalent bond is formed between two atoms (i.e. atom A and atom B) each one providing one electron contained in a partially filled orbital *A covalent bond is a form of chemical bond; formed by the sharing of one or more electrons, especially pairs of electrons, between atoms*.
Example: Consider formaldehyde (H 2 CO) which contains 12 valence electrons. H 2 CO: 2(1) + 4 + 6 = 12 . The formula of this molecule suggests the following skeleton structure. There are three covalent bonds in this skeleton structure, which means that six valence electrons must be used as bonding electrons. This leaves six nonbonding electrons. Ionic bonding is the type of bonding that holds salts together. To better understand why and how ions — atoms that have a charge due to the loss or gain of electrons — are formed, you can study what happens during the chemical reaction to create salt. The components: sodium and chlorine The process of […]

4) A covalent bond in which the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms. 6) An orbital that applies to the entire molecule. 7) A bond angle of 109.5 that results when a central atom forms four bonds directed toward the center of a regular tetrahedron. The bonding electrons in polar covalent bonds are not shared equally, and a bond moment results. However, a molecule may be polar or nonpolar depending on its geometry. For example, tetrachloro-methane (carbon tetrachloride, CCl 4) has polar C—Cl bonds, but the tetrahedral arrangement of the four bonds about the central carbon atom causes the individual bond moments to cancel.
