The Periodic Table—A Preview
A periodic table is an arrangement of elements
in which the elements are separated into groups
based on a set of repeating properties.
A periodic table allows you to easily
compare the properties of one element
(or a group of elements) to another
element (or group of elements).

Types of Elements
Metals
• A metal is an element that is a good electrical
conductor and a good heat conductor.
• Properties of metals
• most are solids at room temperature
• malleable - they can be hammered or rolled into thin
sheets
• ductile - they can be drawn into a fine wire
• conduct electricity and heat well
