Question

An atom contains one more proton than, but the same number of neutrons as, an atom of 29Si. Identify the atom and its nucleon number.

Answer 1

Nucleon number is the sum of the numbers of protons and neutrons. Therefore, for an unknown atom it will be 29 + 1 = 30. An element that contains one more proton than Si is P. So it is ³⁰P.

Answer: ³⁰P
