Question

The transfer of an integral number of __________ is one of the evidence of quantization of electric charge.
Fill in the blank with the correct answer from the options given below.

• A. photons
• B. nuclei
• C. electrons
• D. neutrons

Answer 1

The Correct Option is C

Electric charge is quantized, meaning it exists in discrete units and is measured as integral multiples of a fundamental unit. This fundamental unit is the electron's charge, represented by \( e \). An electron possesses a negative charge of approximately \( 1.6 \times 10^{-19} \) coulombs. Consequently, any total charge \( Q \) can be expressed as \( Q = n \times e \), where \( n \) is an integer. The movement of an integer quantity of electrons serves as proof of electric charge quantization. This principle is fundamental to various electrical and electronic phenomena, as well as theories of atomic structure.
