Answer is: Democritus.
Democritus (c.460 — c.370 BC) was an Ancient Greek philosopher.
According to his atomic theory:
1) everything is composed of atoms.
2) atoms are physically indivisible
3) there is empty space between atoms.
4) atoms are indestructible and in motion.
5) there is an infinite number of atoms, which differ in shape and size.
Democritus was the first to propose the existence of atoms. Option A is the correct answer.
Thus, In contrast to the outdated idea that matter might be divided into any arbitrarily small quantity, atomic theory argues that matter is formed of discrete units called atoms.
It was first introduced as a philosophical idea by Democritus in ancient Greece and India, and it later became a widely accepted scientific theory. Chemical advancements at the time demonstrated that matter did indeed behave as if it were composed of particles.
A fundamental physical quality of matter is mass. The term "atomic mass" refers to the weight of an atom or molecule. To determine the average mass of elements and molecules as well as to resolve stoichiometry issues, the atomic mass is used.
Thus, Democritus was the first to propose the existence of atoms.

Sodium Na is a soft, low-density member of the alkali metal family. The element sodium is a very delicate silvery-white.
Sodium makes up 2.8 percent of the Earth's crust and is the most prevalent alkali metal and sixth most plentiful element on the planet.
A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Typically, metals are malleable and ductile.
Ionic linkages mix metals with non-metals, whereas metallic connections happen between metal atoms. The metallic bonding joins metal atoms.

Answer:
Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.
Explanation:
Hope this helps
