Energy is the ability to accomplish work. All matter is made of fundamental components that cannot be separated into substances with various compounds or actual properties. Components are substances comprising one sort of particles, such as Carbon atoms from diamond and graphite. Unadulterated 24K gold is made from just one kind of particle, gold atoms. Molecules are the littlest molecule into which a component can be separated. This chapter also talks about the difference between atoms and molecules, their characteristics, chemical formulas for common compounds, and 118 elements and their symbols and atomic numbers

The antiquated Greek thinkers built up the atom's idea, even though they thought of it as the essential molecule that could not be separated. Since Enrico Fermi and his associates crafted, we presently realise that the particle is distinct, frequently delivering enormous energies as in atomic blasts or a controlled style in nuclear force plants. Subatomic particles were found during the 1800s. For our motivations? We will focus just on three of them, summed up in Table 1. The proton is situated in the middle or core of a molecule, and every atom has, in any event, one proton. Protons have a charge quantified as +1, and a mass of roughly one nuclear mass unit amu. Components contrast from one another in the number of protons they have, for example, Hydrogen has 1 proton; Helium has 2 protons.
