Atoms Definition & Molecule Definition - Atoms are the smallest particle of an element, which may or may not have an independent existence but always take part in a chemical reaction. Molecules always exist independently and retain their physical and chemical properties.
Define Valency. The combining capacity of an atom is known as its valency. The number of bonds that an atom can form as part of a compound is expressed by the valency of the element. We all know how electrons in an atom are arranged in shells/orbitals. Valence electrons are those electrons which are present in the outermost orbit of the atom.

The process of photosynthesis involves the absorption of CO 2 by plants to produce carbohydrates. The equation is as follows: CO 2 + H 2 O + energy → (CH 2 O) n +O 2. Carbon compounds are passed along the food chain from the producers to consumers. The majority of the carbon exists in the body in the form of carbon dioxide through respiration.
