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
Molecule.
molecule
compound
An ion.
Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.
The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces.
A Molecule
A molecule is formed.
When it's a molecule
The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is a molecule.
A particle composed of one or more atoms is called a molecule
An ion.
Element
It would be an atom or a molecule (made up of more than one atoms)
A molecule; the definition is: The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces.
An atom is the smallest particle there can be and can't be broken down any further while compounds are composed of two or more different atoms of elements.
If it is two or more non-metal atoms bonded together it is a Molecule. If it is two or more types of atoms bonded together, it is a compound. E.g Salt - Sodium and Chlorine.
Two or more atoms joined into a single particle from what
An atom is the smallest particle there can be and can't be broken down any further while compounds are composed of two or more different atoms of elements.
No.an electron is a subatomic particle (it acts like a true "point particle", occupying no volume)a compound is composed of two or more atoms of different elements, these atoms are held together by interactions between their outermost electrons (either electrostatic interactions or quantum mechanical interactions)
