What is the charge value of a proton?

The charge of a proton is indeed valued at 1.6 x 10^-19 coulombs. This fundamental constant is significant in physics, particularly in understanding atomic structure, since protons are positively charged particles found in the nucleus of an atom. The positive charge of protons plays a key role in electromagnetic interactions, particularly in how they attract negatively charged electrons, making them integral to the stability and formation of atoms.

Charges come in discrete quantities, and the charge of the proton is a fundamental unit used for calculations in electrostatics and quantum mechanics. Other options provided do not correspond to the actual charge of a proton, thus highlighting how crucial this precise value is in the study of atomic and subatomic particles.
