Question

which particles are present in the nucleus of an atom​

Answer 1

Protons and neutrons are the two kinds of components that make up an atom's nucleus.

• The atomic number of an element is determined by protons, which are positively charged electrons that are present in the center.
• The uncharged neutrons, which are also present in the center, add to the atom's mass without changing its molecular composition.
• The mass of an atom is determined by the quantity of protons and neutrons in its center. Outside of the centre, electrons, which are negatively charged particles, are located in orbitals or shells.
