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

Text Solution

Verified by Experts

Mass number (A) = 32 , Number of neutrons (N) = 16
Number of protons (Z) `=A-N=32-16=16`
`therefore` Atomic number = 16
The element is sulphur.
The symbol of sulphur is 'S'.
