Introduction
4. The three types of elements: Location of metals, metalloids, and nonmetals
.
Topic 2 - The Periodic Table
Lesson 2 – Types of elements and their Properties
There are three general categories of elements: metal, nonmetals, and metalloids.
The location of an element on the Periodic Table can be used to determine if it is a metal, nonmetal, or
metalloid.
Elements belonging in each category have a set of physical and chemical properties that can be used to
distinguish these elements apart from elements in other categories.
In this lesson, you will learn of the three different types of elements, their location on the Periodic Table,
and their properties.

5. Physical Properties of elements: Definitions and facts of properties of the elements
There are several physical properties that can be used to describe and identify the elements.
The following is a list of physical properties and their definitions.
Concept Facts: Study and to remember these properties.
Malleable describes how easily a solid can be hammered into a thin sheet.
Ductile describes well a solid can be drawn into a thin wire.
Brittle describes how easily a solid can be broken or shattered into pieces when struck by an object.
Luster describes the shininess of a substance.
Conductivity describes the ability to conduct heat or electricity.
Electronegativity describes atom’s ability to attract electrons from another atom during bonding.
Ionization energy describes an element’s ability to lose its most loosely bound valance electrons.
Atomic radius describes the size of an atom of an element.
Density describes the mass to volume ratio of an element
LOOK on Reference Table S to find and compare electronegativity, ionization energy,
atomic radius, and density values of the elements.
