Atoms are the basic unit of chemistry. They consist of 3 smaller things:
Protons - these are positively charged (+)
Electrons - these are negatively charged (-)
Neutrons - these have no charge
These 3 smaller particles are arranged in a particular way. In the center is the Nucleus where you find the positive Protons and neutral Neutrons.
Hydrolysis, in chemistry and physiology, a double decomposition reaction with water as one of the reactants. Thus, if a compound is represented by the formula AB in which A and B are atoms or groups and water is represented by the formula HOH, the hydrolysis reaction may be represented by the reversible chemical equation AB + HOH ⇌ AH + BOH. The reactants other than water, and the products of hydrolysis, may be neutral molecules—as in most hydrolyses involving organic compounds—or ionic molecules, as in hydrolyses of salts, acids, and bases.
Hydrolysis involving organic compounds may be illustrated by the reaction of water with an ester of a carboxylic acid; all such esters have the general formula RCO−OR′, in which R and R′ are
