LIFE SCIENCE

Detailed explanation-1: -The particles that exist inside the nucleus are protons and neutrons but only proton has the positive charge equal to 1.

Detailed explanation-2: -Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite.

Detailed explanation-3: -On the atomic level, protons are positively charged and electrons are negatively charged.

Detailed explanation-4: -A cation is an ion with positive charge, which means it has more protons (positively-charged particles) than electrons (negatively-charged particles). Cations are formed when an atom loses one or more electrons: the loss of the negatively-charged electron(s) results in an overall positive charge.

Detailed explanation-5: -Protons are positively charged and electrons are negatively charged while neutrons have no charge.
