Question

Write the atomic number and the symbol of an element which has mass number $32$ and the number of neutrons $16$ in the nucleus.

Answer 1

Mass number 32

Number of neutrons 16

Mass number = no. of neutrons + no. of proton

32=16+no. of proton

No. of proton = 32-16 = 16

Atomic number is equal to number of proton

So atomic number is 16

An element with atomic number 16 and mass number 32 is sulphur.
