Answer:

The charge of a proton is #+1.602xx10^(−19)# #"Coulombs"#.

Explanation:

And of course the charge on a proton is equal and opposite to the charge on an electron, #-1.602xx10^(−19)# #"C"#.

Note that the sign convention is quite arbitrary. We could equally define the charge as #-1.602xx10^(−19)# #"C"# provided we reversed the sign of the electronic charge. The point is that protons and electrons have #"opposite"# charge.
