A description of the arrangement of elements on The Periodic Table based on electron configuration.

Eric Rosado discusses the key people and discoveries having to do with the periodic table that have molded our understanding of chemistry today. [4:19]

This learning module allows students to use the organization of the periodic table to understand the element and their properties. By the end of the activity, students will be able to locate metals, nonmetals, and metalloids and the...

Video explains why the periodic table devised by Dmitri Mendeleev has endured and how it has predicted the existence of elements. [4:25] Followed by a short quiz and a list of additional resources to explore.

[Free Registration/Login may be required to access all resource tools.] Covers blocks, periods, and the periodic table.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students will explore how the form of the periodic table is related to electron configurations, which in turn influences chemical reactivity.

Given descriptions, scenarios, or groups/series of elements, students will use the Periodic Table to relate the size of the atomic radii, electronegativity, and ionization energy of elements to their position on the chart. Students will...

[Free Registration/Login may be required to access all resource tools.] Students investigate specific properties that can be predicted by an element's position on the periodic table. Additionally, they will look at the formation of ions,...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will sse the Periodic Table to identify and explain the properties of chemical families, including alkali metals, alkaline...

The elements in Group 7 of the Periodic Table are called the halogens. They include chlorine, bromine and iodine. Learn about their properties and uses, then take a quiz.

Given descriptions or specific element groups, students will use a Periodic Table to relate properties of chemical families to position on the table.

Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level. Group 1 elements are reactive metals called the alkali...

This lesson focuses on the periodic table and the configurations. In the modern periodic table, elements are in order of atomic number in periods and groups. Electronic configurations model how electrons are arranged in atoms. A link to...

The number of protons in the atom of an element determines its place in the Periodic Table. The number of electrons in an atom is the same as the number of protons. These electrons are arranged in shells or 'energy levels' around the...

Learn all about the periodic table in this interactive tutorial.

The team at Periodicvideos has created a TED-Ed lesson for every element of the periodic table. This one is about vanadium- element number 23 on the periodic table.
