Detailed explanation-1: -Protons are positively charged and electrons are negatively charged while neutrons have no charge. Protons are not free to move, hence only electrons can move if we provide them enough energy.
Detailed explanation-2: -There are two kinds of electric charge, positive and negative. On the atomic level, protons are positively charged and electrons are negatively charged.
Detailed explanation-3: -electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge.
Detailed explanation-4: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
Detailed explanation-5: -No. Life would be no different if electrons were positively charged and protons were negatively charged. Opposite charges would still attract, and like charges would repel. The naming of positive and negative charge is merely a convention.
