GENERAL KNOWLEDGE

Detailed explanation-1: -Protons and neutrons are subatomic particles that make up the center of the atom, or its atomic nucleus. A proton is positively charged. The number of protons in the nucleus of an atom is the atomic number for the chemical element. Different elements’ atomic numbers are found in the Periodic Table of Elements.

Detailed explanation-2: -Where Are Electrons? Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.

Detailed explanation-3: -The nucleus, with its four protons and five neutrons, is surrounded by a cloud of electrons. In 1911, Ernest Rutherford discovered that at the core of every atom is a nucleus. Atomic nuclei consist of electrically positive protons and electrically neutral neutrons.
