Question

5 example of trivalent elements

Answer 1

5 examples of trivalent elements are :-

* Boron
* Aluminium
* scandium
* Yttrium
* promethium
Extra :- * Lanthanum

Answer 2

The semiconductors are doped with atoms to form p-type region.

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)
