The mass number of an element is 23 and it contains 11 electrons. What is the number of protons and neutrons in it? What is the atomic number of the element?

Give,

The mass number of an element is 23, no. of electrons are 11.


Then the no. of protons are 11. And the no. of neutrons are (23-11) = 12.


The atomic no. of the element is 11.
