Atoms
Atoms are often called the building blocks of matter. They are the smallest units of an element that still retain the properties of that element. They combine to form molecules and various compounds that make up all substances in the universe.
Democritus, a Greek philosopher, is known for his theory of atomism, which proposed that all matter is composed of tiny, indivisible particles called atoms. He also believed in the existence of a void and that the universe was infinite and eternal. Democritus' ideas laid the foundation for our modern understanding of atoms and the nature of matter.
Democritus believed that matter is made of tiny indivisible particles called atoms. He believed that the atoms have always been, and always will be, in motion; that there are an infinite number of atoms, and kinds of atoms, which differ in shape, and size.
Everything is made of atoms, which are the smallest units of an element. Atoms are composed of even smaller particles called protons, neutrons, and electrons.
Atoms are the smallest units of an element. Molecules are the smallest unit of a compound.
When molecules are broken down into smaller units, they are called atoms. Atoms are the basic building blocks of all matter and cannot be further divided into smaller particles without losing their chemical properties.
Physicists get creative in their search for dark matter particles.
All elements are made of basic particles called atoms. Atoms consist of a nucleus, which contains protons and neutrons, surrounded by electrons that orbit the nucleus. These fundamental units combine in various ways to form molecules, leading to the vast diversity of matter in the universe. Additionally, protons and neutrons are themselves made up of even smaller particles called quarks.
The smallest units of covalent molecular compounds are called molecules. They are formed when atoms share electrons to achieve a stable electron configuration.
