Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
A reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.

“Education: that which reveals to the wise, and conceals from the stupid, the vast limits of their knowledge.” ― Mark Twain
The reactivity series, also known as the activity series, is a list of metals arranged in order of their reactivity. In this series, metals are ranked from the most reactive
Synthetic polymerization refers to the process of chemically synthesizing polymers, which are large molecules composed of repeating subunits called monomers.
Radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order
Acidity and basicity are fundamental concepts in chemistry that describe the properties of substances and their behavior in aqueous (water-based) solutions. These concepts are often associated with the pH scale,
