Organizing the Elements Labeling the Periodic Table Properties of M, NM, & Metalloids

I. Labeling the Periodic Table The columns are called groups or families Groups are numbered 1-8 1 8 2 3 4 5 6 7 The rows are called periods Skip these All Elements greater than uranium did not exist on Earth until people produced them in nuclear reactors

I. Labeling the Periodic Table Boron Family Carbon Family Nitrogen Family Oxygen Family Nobel Gases Alkaline Earth Metals Halogens Alkali Metals Transition Metals Rare Earth Elements

I. Labeling the Periodic Table Finally, color the non-metals. Next, let’s identify all the elements that are normally gases by coloring the upper right hand corner with different color. First, let’s identify all the elements that are normally liquids by coloring the upper right hand corner with one of your five colors. Now, let’s identify all the elements that are metals. Remember that metals are found to the left of the stair step line. Color the metals one of your colors. Now, let’s identify all the elements that are diatomic by coloring the lower left hand corner with different color.

II. Properties of Metals Conduct heat and electricity well Called “conductors” Malleable – can be hammered into this sheets Ductile – can be pulled into long thin wires Metals have a metallic luster – they shine when polished

III. Properties of Non-Metals Poor conductors of heat and electricity Called “insulators” Tend to be much more brittle than metal When you hit a non-metal with a hammer it tends to shatter and not flatten out Not ductile or malleable

IV. Metalloids Elements that border the stair step line that separates metals from non-metals are known as metalloids Their properties are a mixture of metallic and non-metallic
