The Periodic Table contains 3 Major Classifications when describing its elements
Concept #1: The Periodic Table of elements can be classified as either metals, metalloids, and non-metals.
Concept #2: Metals represent the largest classification for elements on the Periodic Table
Metals make up the majority of the elements on the periodic table. Using their physical properties we can describe metals as being shiny, conductive, opaque and malleable.
Example #1: Which of the following elements has physical properties most similar to barium, Ba?
Concept #3: Non-Metals represent the second largest classification for elements on the Periodic Table
Non-metals make up the 2nd largest classification and posses physical properties that are opposite of metals.
Concept #4: Metalloids represent the smallest classification for elements on the Periodic Table
Metalloids posses characteristics of both metals and non-metals.
