Chemistry Question on Electronic Configurations Of Elements And The Periodic Table

The magnitude of the charge on the electron is 4.8×10−10 esu4.8 \times 10^{-10}\, esu . What is the magnitude of the charge on the proton on the nucleus of a helium atom ?

A

4.8×10−10 esu4.8 \times 10^{-10}\, esu

B

9.6×10−10 esu9.6 \times 10^{-10}\, esu

C

6.4×10−10 esu6.4 \times 10^{-10}\, esu

D

14.4×10−10 esu14.4 \times 10^{-10}\, esu

Answer

4.8×10−10 esu4.8 \times 10^{-10}\, esu

Explanation

Solution

Charge on the proton is same as on the electron.
i.e., 4.8×10−10  4.8 \times 10^{-10}\,esu
or 1.6×10−19 C 1.6 \times 10^{-19}\,C
