Answer:
Phosphorus
Step-by-step explanation:
From the Bohr model of the given element we can interpret that:
Total number of electron = 15
Total number of proton = 15
Total number of neutron = 16
So, Mass of the element= Total number of proton+ Total number of electron
= 15 + 16
= 31 u
An atom that has 15 electron and mass have mass 31 amu is Phosphorus
