Question

The atomic mass of an element is 32.07 u and its atomic number is 16. The number of protons contained in the nucleus of an atom of this element is
(A) 16
(B) 31
(C) 32
(D) 48

Answer 1

I THINK IT IS 16 BECAUSE THE ATOMIC NUMBER AND THE NUMBER OF PROTONS ARE THE SAME

Answer 2

atomic number = number of electrons = number of protons( by JJ thomson's theory)

Thus, the number of protons is 16
