a) Atomic orbitals can combine two ways, one is additive combination ie, constructive to give Bonding Molecular orbitals. Other way is subtractive combination or destructive way to give antibonding MOs.
The first picture showing the constructive combination of two AOs (1s)to form a Bonding MO (1s). In such combination, the region between the two nuclei has a + sign. This means that the electron charge density between the two nuclei would get intensified.
The second picture shows the destructive combination of two AOs (1s) to form a antibonding MO *(1s). The region of overlap between the nuclei has a - sign. This means that the electron charge density would get removed from the middle of the two nuclei.
