Question

Answer in short what is trivalent elements

Answer 1

Answer:

A trivalent element has three electrons in its valence shell. It shares three electrons with three neighboring silicon atoms in the lattice, the fourth silicon atom demands an electron but the trivalent atom has no more electron to share. This creates a void in lattice which we call it has hole.

I hope this answer will help you.

Answer 2

Answer:

Elements that have their valency as three are called trivalent elements.

Explanation:

When the elements of the third groups are used as the atom to form p-type then they are known as trivalent elements or impurities.

The main trivalent elements are

• boron (Br),

• Aluminium (Al),  

• Indium (In),  

• Gallium (Ga)
• Silicon (Si)
