Question

How many electrons, protons and neutrons are there in a nucleus of atomic number 11 and mass number 24?

Answer 1

Electrons=11

Protons=11

Neutrons=24-11=13

HOPE IT WILL HELP ✌ ✌ ❤

Answer 2

Number of e- = Number of p+

Since atomic number (number of protons) = 11,

∴ No. of e- = No. of p+ = 11.

And, number of n = A (mass number) - Z (atomic number)

⇒ n = 24 - 11

⇒ n = 13.

∴ The number protons, electrons and neutrons are 11, 11, and 13.
