Web1. Explain how the atomic number and mass number of an atom can be used to determine the number of electrons and of neutrons, respectively. In an atom, the components are broadly divided into three main parts, the parts being Electrons, Protons and Neutrons. Protons and neutrons form the nucleus of an atom and contribute to the mass of atoms. … WebThe carbon atom attached to the chain of carbon atoms at the branching point is part of an alkyl group. For example, isobutane is the simplest example of a branched alkane. It has …
