When considering that an electron can be captured by a nucleus can we say that the force applied on the proton by an electron can be viewed as the electron also 'capturing' the proton?
Why so? You can add the same (or equal and opposite) charges to a football and a pea, and a neutron has pretty much the same mass as a proton but no charge at all.
Yes but the charge does not originate in a football or a pea. It originates in a particle.

The equal and opposite charges have always puzzled me
QuoteThe equal and opposite charges have always puzzled me The equal (but opposite) charge on proton & electron has puzzled many theoretical physicists.It has been experimentally confirmed that the elementary charge is equal in magnitude, to within a very small fraction.However, there is apparently nothing the the Standard Model that requires them to be equal in magnitude (but our universe would be very different if they were different!).This hints at a deeper symmetry, below the current Standard Model of subatomic particles.
