Detailed explanation-1: -The proton carries a positive electrical charge that is equal in magnitude to the charge of the electron but opposite in sign. All atoms contain one or more protons. The third subatomic particle of interest to us is the neutron. Its mass of 1.675 X 10-24g is very close to that of the proton.
Detailed explanation-2: -A proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1 and mass slightly less than that of a neutron present in nucleus of every atom. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number (represented by the symbol Z).
Detailed explanation-3: -b) Protons and electrons have opposite charges, as protons are positively charged whereas electrons are negatively charged.
