4 it is!
Here single element semiconductor means pure semiconductor.

Boron and phosphorus are impurity substances which are used to made extrinsic semiconductors, so we are considering si, ge. Please tell is this correct.

If we are considering only the single element semiconductor it means we are talking about the Intrinsic Semiconductor like Silicon(covalent bonding), Germanium(covalent bonding), gallium arsenide (ionic + covalent bonding),etc. These type of elements have 4 electrons in the outer most orbital.
1) silicon:
atomic number =14;.
electronic configuration = 2/8/4.
2)Germanium:
atomic number =32.
electronic configuration = 2/8/18/4.

The Single Element means Made by only Si or Ge. Not Combined.
