Chapter 1: Problem 14

Nucleus of molecule is made up of which fundamental constituents? (a) only Electron (c) Electron and Proton (b) Proton and neutron (d) Electron and neutron

Short Answer

Expert verified
The correct answer is (b) Proton and neutron, as the nucleus of a molecule contains protons and neutrons.

Step by step solution

01

Recall atomic structure

: An atom is made up of three basic particles: electrons, protons, and neutrons. Electrons have a negative electric charge, while protons have a positive charge. Neutrons, on the other hand, are electrically neutral. The nucleus of an atom is located at its center and contains both protons and neutrons. Electrons are found outside the nucleus in atomic orbitals.
02

Determine correct answer

: Since the nucleus of a molecule contains protons and neutrons, the correct answer is (b) Proton and neutron.
