Atom Definition Chemistry. The smallest particle of an element, which may or may not have an independent existence but always takes place in a chemical reaction is called an atom. An atom is defined as the smallest unit that retains the properties of an element. An atom is composed of sub-atomic particles and these cannot be made or destroyed.

Chemistry can be a confusing subject to study. Keeping all of the different terms, theories, and ideas separate in your mind is a real challenge. Even after years of studying the discipline, I still find myself mixing up the basics every now and then. To help you out, I will explain the differences between some of the most fundamental units in chem...
Dictionary definition:the smallest unit of matter that can take part in a chemical reaction and which cannot be broken down chemically into anything simpler. Breaking down the definition:In short, atoms are the tiny pieces of matter that make up our universe. They can't chemically be broken down (the process of atom-splitting is not a chemical one)...
Dictionary definition:a group of two or more atoms bonded together. Breaking down the definition: arguably the simplest molecule in existence, H2, is two hydrogen atoms bonded together. The term 'bonded' is loose and may lead to confusion, so to clear things up we'll define 'bond' in this sense as being a chemical bridge between two atoms that does...
Dictionary definition:a chemical substance made up of two or more elements bonded together, so that they cannot be separated by physical means. Breaking down the definition: this definition is so similar to that of a molecule that it's almost unhelpful, however there is a subtle distinction which serves to separate the two terms. Molecules, as disc...
Atoms are the smallest units of matter that chemists work with; collections of subatomic particles that can be categorised into unique elements based on the number of protons in their nucleus. Molecules are a step up; a collection of two or more atoms held together by covalent bonds, such as hydrogen gas or H2. Compounds are very similar to molecul...

Molecules, in general, are the smallest entities that can represent the chemical properties of a compound. It is strange to define a molecule using a compound, and then a compound using the idea of molecules, but they are so interconnected that it is difficult to find independent definitions. (The picture is made clear when a compound is defined.)
- The Atomic Theory of Matter. Dalton’s atomic theory of matter: Each element is composed of extremely small particles called atoms. All atoms of a given element are identical; the atoms of different elements are different and have different properties.
- The Discovery of Atomic Structure. subatomic particles – what atoms are composed of. Like charges repel each other; unlike charges attract. Cathode Rays and Electrons.
- The Modern View of Atomic Structure. charge of an electron is –1.602*10-19. charge of a proton is +1.602*10-19. 1.602*10-19 is called to electronic charge.
- Atomic Mass. all atoms of an element have the same number of protons in the nucleus. isotopes - atoms of the same element that have a different number of neutrons.
- Key points. atom The smallest particle of an element. We often think of atoms as tiny spheres, but in fact they are made from smaller particles called protons, neutrons and electrons.
- Atoms. Atoms are the building blocks of all matter. Everything is made of atoms - even yourself. Atoms are the smallest particle of an element A pure substance which is made from only one type of atom.
- Molecules. Molecules are made when two or more atoms chemically bond together. Atoms from different elements can combine. When the atoms are from different elements, the molecule can also be called a compound.
- Drawing atoms and molecules. Atoms can be drawn as circles. But all the atoms of an element need to look exactly the same. When drawing a diagram of molecules made from the atoms of more than one element, different sizes and colours can show the different elements.
Aug 17, 2024 · atom, the basic building block of all matter and chemistry. Atoms can combine with other atoms to form molecules but cannot be divided into smaller parts by ordinary chemical processes. Most of the atom is empty space. The rest consists of three basic types of subatomic particles: protons, neutrons, and electrons.

Apr 28, 2024 · 2.4: Atomic Mass. The mass of an atom is a weighted average that is largely determined by the number of its protons and neutrons, and the number of protons and electrons determines its charge. Each atom of an element contains the same number of protons, known as the atomic number (Z). Neutral atoms have the same number of electrons and protons.
