Question : What are the components of the nucleus of an atom?
Option 1: Only protons
Option 2: Protons and neutrons
Option 3: Neutrons and electrons
Option 4: Only neutrons
Correct Answer: Protons and neutrons
Solution : The correct option is Protons and neutrons
The core, a dense portion of an atom that contains positively charged protons and uncharged neutrons together with most of the atom's mass, is called nucleus. A cloud of negatively charged electrons occupying various energy levels or orbitals surrounds the nucleus. A nucleus comprises protons and neutrons that determine the identification of an element and impact its properties. An atom's behaviour, stability, and participation in chemical reactions are referred to by its interactions within the nucleus and with its surrounding electrons.
