Question

25. The charge of an electron is 1.6 x 10 coulombs. What will be the value of charge on Na+ ion 1) 1.6x10- 2) 3.2x10-c 3) 2.4x10-9c 4) 11x1.6x10-19​

Answer 1

Answer:

The charge of an electron is 1.6 x 10^-19 coulombs.

The Na+ ion has lost one electron from its outermost shell, so its charge is +1. Therefore, the value of charge on Na+ ion is:

Charge on Na+ ion = +1 x (1.6 x 10^-19 C)

Charge on Na+ ion = 1.6 x 10^-19 C

Therefore, the value of charge on Na+ ion is 1.6 x 10^-19 C.

Hence, the correct option is 1) 1.6x10^-19 C.
