There are 15 protons and 16 neutrons in the nnucleus of an element .Calculate its atomic number and mass number .How will you represent the element?

Text Solution

Verified by Experts

Atomic number of the element = No of porotns=15
Mass number of the element =No of protons (15)+ No of neutrons (16)
=15+16=31
Representation of the element =` overset(31)underset(15)X`
The element with atomic number (Z=15) is actually phosphorus (P).It is represented as `overset(31)underset(15)P`
