The periodic table is arranged by atomic number, which is the number of protons in an element’s nucleus. The elements are arranged in order of increasing atomic number. The periodic table is also arranged by groups and periods. The...

Valence electrons are the electrons that are located in the outermost shell of an atom. In other words, these are the electrons that can be gained or lost during a chemical reaction. In order to determine the number of valence electrons...

Atoms and Elements: Defining Terms distinguishes the differences between an atom, an element, a molecule, and a compound.

Using Isotopes explores isotopes by describing how isotopes are used in scientific research and medicine.

This video will explain the concept of a mole and how to convert between moles, grams, and atoms.

The Periodic Table: Atomic Number examines the Periodic Table of Elements and uses the atomic number to identify the number of protons, neutrons, and electrons in a given element.

This video explains how the different particles in an atom have charges, how the different particles affect the overall charges of an atom, and how atomic models are created.

Explains how to compose an electronic configuration for an element using the number of electrons that the element has.
