Question

The energy gap is much more in silicon than in germanium because
It has less number of electrons
o
It has high atomic mass number
Its crystal has much stronger bonds called ionic bonds
Its valence electrons are more tightly bound to their parent nucli​

Answer 1

Answer:

A It has less number of electrons.

B It has high atomic mass number.

c Its crystal has much stronger bonds.

Answer 2

Answer:

 The valence electrons in silicon are more tightly bound because their atomic radius is small.

Explanation:

• The behavior of semiconductors depends upon the extent of the energy gap between the valence band and conduction band.
• Thus, the valence band and conduction band to the parent nuclei in the case of silicon as compared to germanium.
