#+3# charge

A mass of #20 \ "u"#

You have the element with #14 \ "P"#, #6 \ "N"#, and #11 \ e^-#. I'm assuming by #"P"# you meant protons.

So, this atom has #14# protons, #6# neutrons, and #11# electrons.

Each proton has a charge of #+1#, while each electron has a charge of #-1#. Neutrons have no overall charge.

So, the total charge is: #1*14+(-1)*11#

#=14-11#

#=3#

The atom's total charge turns out to be #+3#.

The total mass of an atom is equal to the total sum of protons and neutrons. Therefore, this atom's total mass is #14+6=20# atomic units.
