TOPIC : Metals _____________________________________________

Summary
An element that typically is a hard, shiny solid, is malleable and is a good conductor of heat and electricity. The metal groups include Transition metals, Alkali metals, and Alkaline Earth metals

Key Terms
1.Malleable- if it can be hammered into a sheet and makes coins and tubing

2.Ductile- if it can be made into a wire

3.Metalic Bonding- metal and metal bonding, sea of electrons

Other Topics it relates to: Iron triad, coinage metals, Zinc, Cadmium and Mercury, Lanthanides and Actinides

Conductor or insulator Conductor Insulator
Appearance when a solid Shiny, ductile Brittle and dull

Applications: Metals are used in construction because it is very hard, malleable and ductile. Alkaline Earth metals are used in fireworks because they are reactive.

Memory Aid: Flipper book

What Mr. Kremer might ask (or has asked): Define Malleable and ductile. How are these properties of metal useful?

It was invented by Dmitri Mendeleev in 1869. Each little box of an element, has the name of the element, the atomic number, atomic symbol, and atomic mass. They are each categorized in groups numbering from 1-18. The periodic table is a nice organized way to present your elements. olivia emma and andye The periodic table is a chart of elements organized in groups and periods according to their mass, their structure, their atomic number, and their classification.
