Detailed explanation-1: -An atom is the smallest unit of matter that retains all of the chemical properties of an element.
Detailed explanation-2: -The number of protons is very important in the atom as it gives the atom its identity. An atom with only 1 proton will be identified as a hydrogen atom; an atom with 6 protons will be identified as a carbon atom and so on. The number of protons in an atom determines its elemental identity.
Detailed explanation-3: –Atoms retain their identity in all chemical reactions. This is basically the Law of Conservation of matter stating that an equal amount of mass exists before and after a reaction.-Atoms combine in fixed ratios of small integers to form compounds. This is close to the Law of Definite Proportions.
Detailed explanation-4: -An atom is the smallest particle of an element that retains its identity in a chemical reaction. If an atom is broken down further, one will get protons, neutrons, and electrons. Each element’s atom has a unique number and combination of these three particles that constitute the atom’s identity.
Detailed explanation-5: -It is made up of only one type of particle. As an element cannot be broken down further, it is the simplest form of matter. Example: Iron, Copper, etc.
