Problem 7.75 Until the early 1960s, the group 8A elements were called the inert gases. (a) Why was the term inert gases dropped? (b) What discovery triggered this change in name? (c) What name is applied to the group now?
Step-by-Step Solution:

Step 1 of 5) The lower-energy MO concentrates charge density in the region between the nuclei and is called a bonding molecular orbital. The higher-energy MO excludes electrons from the region between the nuclei and is called an antibonding molecular orbital. Antibonding MOs exclude electron density from the region between the nuclei and have a nodal plane—a place at which the electron density is zero—between the nuclei. Occupation of bonding MOs favors bond formation, whereas occupation of antibonding MOs is unfavorable. The bonding and antibonding MOs formed by the combination of s orbitals are sigma 1S2 molecular orbitals; they lie on the internuclear axis. The combination of atomic orbitals and the relative energies of the molecular orbitals are shown by an energy-level (or molecular orbital) diagram. When the appropriate number of electrons is put into the MOs, we can calculate the bond order of a bond, which is half the difference between the number of electrons in bonding MOs and the number of electrons in antibonding MOs. A bond order of 1 corresponds to a single bond, and so forth. Bond orders can be fractional numbers.
