CHEMICAL BONDING Lesson Plan By: Mrs. Aqeela
What are atoms? • 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
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.
Chemical bonds: • 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.
