Question

The nucleus of the element having atomic number 23 and atomic weight 55 will contain?

Answer 1

Answer:   The nucleus will contain  32  neutrons.

(Hope your question was asking about the no. of neutrons)

Explanation:,

No. of protons = atomic no. = 23

Atomic mass = no. of protons + no. of neutrons

=>  55  =  23 + n          (n = no. of neutrons)

So,  n = 55-23 = 32
