The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. Also, a molecule is formed when two or more atoms are chemically combined together.What is the simplest way of explaining what atoms, elements, compounds and mixtures are?Ītoms are the smallest bits of ordinary matter and are made from particles called protons (which carry a positive electrical charge), neutrons (which carry no electrical charge) and electrons (which carry a negative electrical charge). What is the difference between Atoms and Molecules?Īns: Atoms are defined as the smallest unit of an element, whereas a molecule is the smallest unit of a compound. Molecules are also divided as a molecule of the compound, a molecule of an element. Just like how in a building, brick is the most fundamental substance combining with other bricks to make the building or how a tiny grain of sand is nothing in itself but can create a whole dessert altogether when many of them combine.Īns: Molecules can be defined as the basic unit of compounds composed of more than one atom chemically bonded together, forming a pure substance with no net charge over it. Atoms can be considered the basic unit of matter on a micro-level, creating a substance by combining with many similar atoms. For example, A water molecule is a molecule of a compound where the molecule has two hydrogen atoms and one oxygen atom, two different elements, \(\mathrm\right)\).Īns: Atoms are the basic building blocks of matter around us from which matter is made.
