Question

Calculate the atomic mass of Boron?​

Answer 1

Atomic mass is the sum of number of protons and of neutrons.

Boron contains five protons and six neutrons in it.

So, it's atomic mass is 11.

i.e.

Atomic Mass of Boron = Number of protons + Number of neutrons

=> 5 + 6

=> 11 u (amu)

$\textbf{Atomic Mass of Boron is}$

$\textbf{11 u (amu)}$
