Atom Molecule Element Compound
1 Answer
Atom is a particle of matter that characterizes a chemical element.
- Atoms, Elements, Molecules, Ions, and Compounds. Early in the 19th century John Dalton developed atomic theory. His theory explained the best available experimental data at that time. His theory has been modified since then with the discovery of other data, but his work was the initial ground work that we will examine first.
- Atoms, Elements, and Compounds Section 1. Reactants and Products! A chemical reaction is the process by which atoms or groups of atoms in substances are reorganized into different substances. Chemical Reactions! Clues that a chemical reaction has taken place include.
- A compound can be separated into the individual elements that it is comprised of and an element can separated as far as its individual atoms. An atom represents the smallest possible part of an element that still retains the properties of that element.
Explanation:
An atom is a particle of matter that characterizes a chemical element. It is the smallest part of ordinary matter. It is made from particles called protons, neutrons and electrons called the subatomic particles.
An element is a substance that is made entirely of one type of atom. For example, the element sodium is made up of only sodium atoms.

A molecule is a substance that contains two or more atoms chemically joined, such as #H_2, O_2#
A compound is a substance that is made up of two or more different elements that are chemically joined, such as #H_2O, CO, NaCl# .
Note: All compounds are molecules, but not all molecules are compounds.
