Molecule
The term for the simplest representative particle in a compound composed of nonmetal atoms is a molecule. A molecule consists of two or more nonmetal atoms chemically bonded together.
Atoms
If a term consists of one or more of: a numerical coefficientnon-negative integer exponents of variable(s),then it is a term of a polynomial. If a term consists of one or more of: a numerical coefficientnon-negative integer exponents of variable(s),then it is a term of a polynomial. If a term consists of one or more of: a numerical coefficientnon-negative integer exponents of variable(s),then it is a term of a polynomial. If a term consists of one or more of: a numerical coefficientnon-negative integer exponents of variable(s),then it is a term of a polynomial.
The term "basic unit of matter" refers to an atom, which is the smallest unit of an element that retains the properties of that element. Atoms are composed of protons, neutrons, and electrons.
Matter is any substance that has mass and occupies space. It consists of atoms and molecules that interact to create different forms and properties. While matter can undergo changes, the ability to cause change is generally attributed to energy.
The meaning is that atoms and molecules are permanently in motion.
A molecule is the term that describes a combination of two or more atoms bonded together.
This sounds to me like you are wanting the term "molecule". A molecule is a group of atoms bonded together.
The term molecule or compound best defines two or more atoms joined by a chemical bond.
When matter contains only one species of atom (same number of protons in nucleus of each), it is called an element.Related Information:Each element is made of atoms that are essentially the same, with the same number of protons in the atomic nucleus. An element may have stable forms with varying numbers of neutrons, and these are called isotopes.Elements are classified as pure substances, a type of matter that cannot be chemically separated into other components. Matter that consists of only one type of atom (for instance iron, Fe) is called an element. Matter that consists of two or more types of atoms, chemically combined (for instance table salt NaCl, sodium and chlorine combined) is called a compound
Democritus proposed that all matter is made up atoms and he coined the term "atomos", or atoms, which means indivisible. He claimed atoms could not be destroyed and that matter would remain the same, even if it is sliced into the smallest possible quantity.
A substance composed of two or more atoms of the same element is just a pure substance/element, a substance composed of different atoms is called a compound
