Detailed explanation-1: -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.
Detailed explanation-2: -The nucleus (or center) of an atom is made up of protons and neutrons. The number of protons in the nucleus, known as the “atomic number, ‘’ primarily determines where that atom fits on the Periodic Table.
Detailed explanation-3: -Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.
