What kind of molecular orbital would result when atomic orbitals are combined as indicated?

Provided question is incomplete as it lacks image or diagtram related to the question, however the correct indication is attach with answer :

The correct answer is : antibonding molecular orbital

Explanation:

At the point when two atomic orbitals can consolidate directly produce two molecualr orbital, of which one is holding sub-atomic orbital of lower vitality and the other antibonding molecular orbital of higher energy.  

Holding molecular orbital would by and large outcomes which nuclear orbitals of same phase joins while antibonding molecular orbital would results when atomic orbitals of various stages can combine.  

In the given approach, it is obvious that one of S - orbital is going consolidate directly with opposite phase of p - orbital along their inter nuclear axis. Subsequently it prompts the formation of sigma antibonding molecular orbital.

Thus, the correct answer is : antibonding molecular orbital

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
