Periodic Table Basics

Click on the flashcard to see the answer



What is the periodic table?

The periodic table is a tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

What is a group in the periodic table?

A group is a vertical column in the periodic table, and elements in the same group typically share similar chemical properties.

What is a period in the periodic table?

A period is a horizontal row in the periodic table. Elements in the same period have the same number of atomic orbitals.

Name the three main categories of elements found in the periodic table.

The three main categories are metals, non-metals, and noble gases.

What are transition metals and where are they located in the periodic table?

Transition metals are elements located in groups 3-12 of the periodic table and are known for their ability to form variable oxidation states.
