Chapter 2, Problem 2TY
Summary Introduction
Introduction: Atom is the smallest structural unit of any matter. The nucleus is the centermost part of the atom. The atom consists of proton, electron and neutron. Multiple numbers of atoms are joined together and form the molecules. The presence of shells and orbitals are found in the structure of the atom.
