Which of the following statement is correct about the atom of an element?(a) an atom can have only protons and neutrons but no electrons.(b) an atom can have only electrons and neutrons but no protons(c) an atom can have only electron and proton but no neutron(d) an atom must always have a proton, neutron and electron
Correct Answer: (c) an atom can have only electron and proton but no neutron
Explanation: An atom must have a proton and an electron, but it may not have a neutron. For example, in the hydrogen atom, there is 1 proton, 1 electron but no neutron.
