An element is a fundamental substance that cannot be broken down into simpler substances by chemical means and is defined by its number of protons in the atomic nucleus. Elements are the building blocks of matter, each with unique properties that determine their role in chemical reactions and the formation of compounds.

number of protons

The atomic nucleus is the small, dense region at the center of an atom, composed of protons and neutrons, which together account for nearly all of the atom's mass. Its stability and interactions are governed by the strong nuclear force, which is much stronger than the electromagnetic force that would otherwise cause the positively charged protons to repel each other.

Chemical reactions involve the transformation of substances through the breaking and forming of chemical bonds, resulting in the conversion of reactants into products. These reactions are governed by the principles of thermodynamics and kinetics, which dictate the feasibility and rate of these transformations.
