Atoms are the tiny basic building block of matter.
All the material on Earth is composed of various combinations of atoms.
Atoms are the smallest particles of a chemical element that still exhibit all the chemical properties unique to that element
Structure of atoms:
What are molecules?
The concepts of atoms and of the groups of linked atoms called molecules are the foundation of all chemistry .
An atom is the smallest unit of an element that has the properties of the element; a molecule is the smallest unit of a compound or the form of an element in which atoms bind together that has the properties of the compound or element.
A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms.
The bond is caused by the electromagnetic force attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction.
The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions, the London dispersion force and hydrogen bonding.
