Solution

Protons
Electrons
Neutrons
Protons are positively charged particles. Electrons are negatively charged particles. Neutrons are neutral particles which mean that they have no charge.
They are present inside the nucleus. They are present outside the nucleus and revolve around the nucleus. They are present inside the nucleus.
They have a mass of $1.67 \times 10^{- 27} k g$ . They have a mass of $9.1 \times 10^{- 31} k g$ They have a mass of $1.67 \times 10^{- 27} k g$ .
Protons are represented as $p^{+}$ Electrons are represented as − $e^{-}$ Neutrons are represented as $n$
A proton is said to be very stable whether it's in its free state or inside the atoms. They do not decay spontaneously. Electrons are stable. An atom is said to be stable if its outermost shell has electrons to complete the octet. They are unstable and decay liberating beta particles.
The atomic number of an element is equal to the number of protons in the atom. The number of electrons and protons are equal in a neutral atom. The mass number of an atom is the sum of number of protons and number of neutrons.
