Question

The charge of an electron is
1. 1.602 × 10^-19 coulomb
2. 6.24 × 10^-18 coulomb
3. 6.24 × 10^-19 coulomb
4. None of the above

Answer 1

Correct Answer - Option 1 : 1.602 × 10^-19 coulomb

Charge on an electron is 1.602 x 10-19 C.

Charge:

• There are two kinds of charge, positive and negative.
• Like charges repel, unlike charges attract.
• The positive charge comes from having more protons than electrons.
• A negative charge comes from having more electrons than protons.
• A charge is quantized.
• A charge is conserved.

q = n e

q is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10-19 Coulombs.​

Particle	Charge (C)	Mass (Kg)
Proton p+	+ 1602 × 10-19	1.67 × 10-27
Neutron n0	0	1.67 × 10-27
Electron e-	-1.602 × 10-19	9.11 × 10-31
