a) Bismuth
b) Silicon
c) Germanium
d) Both b&c​

Answer 1

Answer:

d)

Explanation:

There are two blanks given so it is clear there are two substances which are silicon and germanium

Answer 2

Research In Chemistry has Provided Versatile Materials Such as silicon and germanium which are widely used in making diodes.

• Germanium and silicon are used in making diodes and are elements of group 14 of the periodic table.
• Silicon and germanium both have 4 electrons in their valence shell as belonging to 14 groups of the periodic table.
• Both can lose or gain electrons to attain noble gas configuration. so, they are used in semiconductors or diode formation.
• Silicon is cheap and the silicon diode can be produced easily with easily available raw materials.
