Question

mass number of e is 37 and atomic number of e is 17 how many electrons are there in an atom of e​

Answer 1

Answer:

Given - Atomic number of element = 17

                               Mass number of element = 37  

                               Number of electrons = 17

As we know, number of protons is equal to number of electrons.

so,                  number of protons = 17

now,  Mass number = number of protons + number of neutrons

        37 = 17 + number of neutrons

         number of neutrons = 37 - 17

          number of neutrons = 20

So, the number of neutrons in the nucleus = 20.
