BONDING

Lesson Plan

By:

Mrs. Aqeela


What are atoms
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
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
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.
