Democritus was the one who came up with the concept and the name (atomos in Greek means "no-cut"). Democritus was mostly lucky, not prescient; the scientific method in ancient Greece largely consisted of coming up with as many wacky ideas as they possibly could, under the theory that eventually someone's wacky idea was bound to be right.
The concept of an atom as an indivisible component of matter was first proposed by early Indian and Greek philosophers. In the 17th and 18th centuries, chemists provided a physical basis for this idea by showing that certain substances could not be further broken down by chemical methods. During the late 19th and early 20th centuries, physicists discovered subatomic components and structure inside the atom, thereby demonstrating that the 'atom' was not indivisible.
The earliest references to the concept of atoms date back to ancient India in the 6th century BCE. The Nyaya and Vaisheshika schools developed elaborate theories of how atoms combined into more complex objects (first in pairs, then trios of pairs). The references to atoms in the West emerged a century later from Leucippus whose student, Democritus, systemized his views. In approximately 450 BCE, Democritus coined the term átomos (Greek: ἄτομος), which means "uncuttable" or "the smallest indivisible particle of matter", i.e., something that cannot be divided. Although the Indian and Greek concepts of the atom were based purely on philosophy, modern science has retained the name coined by Democritus.
Democritus and/or his mentor Leucippus came up with the idea, but for them it was a really lucky guess; they had no evidence for this (and they were completely wrong about what the atoms were actually like).
The modern concept of atoms dates back to John Dalton, who unlike them had an actual reason for suspecting this was true.
Dalton suggested that matter was made up of atoms in his Atomic Theory.

Solid is the densest state of matter because the atoms are packed tightly together in a solid.
solid
All matter is made of atoms. Liquids, solids and gases are all made of atoms. It is the bond between atoms that make a substance solid or liquid.
The arrangements of atoms and molecules give matter properties. Each arrangement is called a ''state of matter". A solid is matter that has a definite shap and takes up a definite amount of space. Vintage Magnet Student 4th Grade Mrs.Bhattacharyra Room 28
So I had this question for school. I looked it up here and in the textbook. So for one thing matter can be in the form of; a solid, a liquid, or a gas (that is not what its made of tho). Matter is made up of molecules, and atoms. So don't put down on your final exam that matter is made up of solid, liquid, and gasses. MATTER IS MADE UP OF MOLECULES AND ATOMS!!

a solid
Matter that has a definite shape and volume is in solid state.
A solid is matter with atoms tightly packed together.
Matter is a combination of atoms, often molecules, that are in a solid, liquid, or gas phase.

solid state
Solid, liquid, and gas states of matter are composed of neutral atoms or molecules. Plasma is the state of matter composed of highly ionized atoms and free electrons.
The state of matter that keeps atoms together is solid. Liquids and gases allow atoms to break apart from each other.
The same particles of matter that make up a solid are also the same particles of matter that make up a gas or a liquid. Basically matter consists of atoms. At the simplest level, the particles of atoms are electrons, protons and neutrons.
