Hey There! This is your required Answer ↓↓↓↓

• Atom → An atom a fundamental piece of matter. It itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons


• Molecule → A molecule is a particle made up of two or more atoms that are chemically bonded together.

Hi

Here's your answer

There are lots of terms in chemistry that can be easy to mix up: atoms, molecules, compounds, mixtures, and more. In this lesson, we'll go through some of the basics of atoms and molecules, and define all of the important terms you need to know.

Atoms

Atoms are the basic building blocks from which everything around us is built. This includes the computer before you, the floor beneath you, the air you breathe, and the stars you see at night. All of them are made up of atoms. But what exactly are atoms?

Atoms are made up of three types of tiny particles. Protons (or positively charged particles) and neutrons (or particles that contain no charge) are found in the nucleus of an atom. Electrons (or negatively charged particles) are found outside the nucleus. There are 118 elements, or substances composed of a single type of atom, on the periodic table, including hydrogen, carbon, lead, gold, lithium, oxygen, and more.

Molecules, Compounds, & Mixtures

Atoms can bond together into groups and form a molecule. If the molecule contains atoms of different types bonded together, we call it a compound. For example, two hydrogen atoms and one oxygen atom bonded together creates the compound water. Bonding is vital for life; you wouldn't be reading this lesson without it.

Mixtures are what you get when you combine several compounds. No bonding or chemical reactions are involved in creating a mixture. For example, if you take water and mix it with a packet of flavoring, you get a refreshing drink. But, the molecules are really just interspersed between each other; no bonding has taken place.
