Question

The number of semiconductors in periodic table is
(a) 3
(b) 5
(c) 7
(d) 13.​

Answer 1

The number of semiconductors in the periodic table is 13.

• Semiconductors are materials with electrical conductivity between that of conductors (such as metals) and insulators (such as ceramics). They play a crucial role in many modern technologies, including computer chips and solar cells. The most common semiconductors are silicon (Si), germanium (Ge), and gallium arsenide (GaAs).

• Semiconductors are materials that have electrical conductivity between that of conductors and insulators. They are used to make electronic devices such as transistors, diodes, and integrated circuits, which form the backbone of modern electronics. Semiconductors can be manipulated to control the flow of electricity, making them versatile in applications such as computer processors, solar panels, and telecommunications devices.
• Semiconductors are made of elements from Group 14 of the periodic table and typically have 4 electrons in their outermost energy level, making them ideal for controlling electrical conductivity.
