Notes 4-3 and 4-4 Metals, Nonmetals, Inert Gases and Semimetals
Slide 2 Metals Physical Properties Malleable Magnetic Ductile
Thermal conductivity Electrical conductivity Chemical Properties
Reactive Corrosive Slide 3 Types of Metals Most of the Periodic
Table is made up of metals!!! Alkali Metals Group 1; most reactive
group of elements Alkaline Earth Metals Group 2 Transition Metals
Groups 3-12 Metals in Mixed Groups Groups 13-15 Special Cases:
Lanthanides Similar properties to Group 2 elements Antinides most
created artificially in labs; unstable nuclei Synthetic Elements
atomic numbers higher than 92; made by scientists by forcing
nuclear particles to crash into one another Slide 4 Nonmetals Slide
5 Inert Gases Group 18!!! Tend to be UNreactive Slide 6 Hydrogen
Element with the simplest atoms Very different from atoms of other
elements so not in a family Makes up more than 90% of the atoms in
the universe Makes up only 1% of Earths crust Rarely found on Earth
in its pure form Most hydrogen is combined with oxygen in water
Slide 7 Semimetals Also called metalloids Some of the properties of
both metals and nonmetals Most useful property is their ability to
conduct electric currents
