# Electron Configuration and Binding [closed]

Boron with an electron configuration of $1s^22s^22p^1$ has an atomic weight of $10.811u$. What is the total binding energy for 11Bs if $Mn = 1.008665u$ and $Mp = 1.007825u$.

I cannot find anything online to help me solve this. I need a formula to solve this, but I do not have that.
