Question

What will be the mass number of an element having atomic no 15 and no of neutrons is 16??? Please provide step by step explanation

Answer 1

Answer:

31amu

Explanation:

The element is phosphorus, since the atomic number of phosphorus is 15 it will be the same for its no. of protons. It is given that the number of neutrons is 16 ,

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

                         15+16 = 31

Therefore, the atomic mass of phosphorus is 31 amu .

i hope it helps
