Question

What is the number of electrons, protons and neutrons. If Z=25 and A=49 ? A.p=49 , e=25 , n=24 B.p=25 , e=24 , n=25 C.p=49 , e=49 , n=24 D.p=25 , e=25 , n=24​

Answer 1

Answer:

Option D is correct ✅

Because number of electron is equal to the number of proton and number of proton and electron is equal to the atomic number so by this concept all options are eliminated except option D.

Z = atomic mass
