Atoms are the basic units of matter and the defining structure of elements. The term “atom” comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. Atoms were created after the Big Bang 13.7 billion years ago.

But when it comes to the word atom, we have to go to ancient Greece of 400 B.C. And there was a brilliant philosopher named Democritus, and he proposed the Greek word atomos, which means uncuttable. And so as he explained, all matter was eventually reducible to discrete, small particles or atomos.

Atoms were impenetrably hard, meaning they could not be divided. In Greek, the prefix “a” means “not” and the word “tomos” means cut. Our word atom therefore comes from atomos, a Greek word meaning uncuttable. The word is derived from the Greek word “atomos”, meaning indivisible.

An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.

What Are The 5 Parts Of An Atom

• Protons.
• Neutrons.
• electrons.

Answer. water is liquid . ACC. to state of matter which is solid , liquid or gas .

Answer. Answer: One common characteristics of fluids is that they do not have a fixed shape and are easily deformed.In space, liquids tend to take the form of a sphere, while gases seem shapeless. under the influence of gravity liquids take on the shape of the container, while gasess often flow out of any container.

Solid, Liquids, and Gases. Sold, liquid, and gas all have volume and shape. They are all made up of atoms, molecules, or ions. Liquids and solids can be referred to as condensed phased because their particles are close together. Liquids and gases flow easily because their particles can move or slide past one another.

Write any five characteristics of solid, liquid, and gases.

• solid have a fixed shape and a fixed volume.
• solid cannot be compressed.
• solids have high density.
• force of attraction between the particles is very strong.
• The space between the particles of solids is negligible.

(Entry 1 of 2) 1 : a fluid (such as air) that has neither independent shape nor volume but tends to expand indefinitely. 2a : a combustible gas or gaseous mixture for fuel or lighting especially : natural gas. b : a gaseous product of digestion also : discomfort from this.

Examples of Gases

• Hydrogen.
• Nitrogen.
• Oxygen.
• Carbon Dioxide.
• Carbon Monoxide.
• Water Vapour.
• Helium.
• Neon.
