As opposed to bonding in which a complete transfer of electrons occur, bonding occurs when two or more elements electrons. Covalent bonding occurs because the atoms in the compound have a similar tendency for electrons (generally to electrons). This most commonly occurs when two bond together. Because both of the nonmetals will want to electrons, the elements involved will share electrons in an effort to their valence shells.

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
