GEOLOGY

Detailed explanation-1: -Protons are particles which have a positive charge and are massive nuclear particles. The number of protons present in the nucleus of an atom define the atomic number which is the identity of that element. The sign of the charge of the proton is generally positive.

Detailed explanation-2: -The positively charged subatomic particle is known as a proton.

Detailed explanation-3: -Protons are positively charged and electrons are negatively charged while neutrons have no charge.

Detailed explanation-4: -Neutrons, along with protons, are subatomic particles found inside the nucleus of every atom. The only exception is hydrogen, where the nucleus contains only a single proton. Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than positively charged protons.

Detailed explanation-5: -As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged. The negative charge of one electron balances the positive charge of one proton. Both protons and neutrons have a mass of 1, while electrons have almost no mass.
