Let’s learn about your periodic table! You might need a red, orange, yellow, green, blue, purple and black colored pencil. SHARE PENCILS!!! Highlighters also work!!!

Let’s start by outlining the metals yellow… Just OUTLINE!!!

Metal Elements Malleable - Squishable Ductility – Can become wires Metals: Elements that: Conduct electricity and heat quickly Shiny Malleable - Squishable Ductility – Can become wires (Remember we covered these in chapter 5!)

Next, let’s outline the metalloids pink/purple… Notice the stair pattern.

Metalloids Metalloids: Elements that have some metal properties and some nonmetal properties. Example Silicon (Si). Shiny like a metal, but very brittle and it does not conduct electricity.

Next, let’s outline the nonmetals green.

Non-Metals Nonmetals: Elements that are: Poor conductors of electricity and heat Dull in color Not easily shaped. They break easy or they are a gas, and gases do not have a shape!

Next, let’s outline the “unknowns” grey.

Unknowns Unknowns- Elements that are synthetic (made in a laboratory) and still need to be tested to be approved as an element.

Groups and Periods Groups are the columns on the periodic table. (Up/down) Groups are also called “family of elements” Elements in the same group have similar chemical properties. They like to react in the same way with the same elements. Their physical properties can be different!

Periods are the rows (left/right) Periods show electron energy cloud “shells” Basically, periods show elements that have similar electron clouds. Empty shells Full Shells

Remember where Groups are! 1 18 13 14 15 16 17 2 3 4 5 6 7 8 9 10 11 12

And Periods!!! Periods Periods 1 18 1 13 14 15 16 17 2 2 3 3 4 5 6 13 14 15 16 17 2 2 3 3 4 5 6 7 8 9 10 11 12 4 5 6 7 Periods 6 7

Names of the Groups Group 1 and 2: The Reactive Metals Group 1 is composed of the “alkali metals”. These alkali elements are highly reactive. They want to combine with other elements. They have to be stored away from air and water! HYDROGEN is not a metal!!!

Color the Alkali Metals Color the alkali metals RED. Just shade in their boxes H

Group 2 Group 2 is composed of the “alkaline earth metals”. Alkaline earth metals are less reactive than group 1, but still like to combine with other elements.

Color the Alkaline Earth Metals Now color the alkaline earth metals ORANGE.

Groups 3-12: Transition Metals Metals that are not very reactive. Includes most major metals: Gold, Silver, Iron, Copper. Transition metals are used in industry (making stuff) Bonus Info: Most transition metals get mixed together to form an alloy which is stronger then a pure element. EX: Steel is iron mixed with nickel and chromium. Brass is copper mixed with zinc.

Transition Metals The transition metals are the white squares. 3 - 12

Group 18: The Noble Gases These elements do not react with other elements. Often called “inert” gases. Meaning “unable to move or act”. Found in the atmosphere. When hit with electricity, they glow… like neon lights.. Ne… Neon…

Noble Gases Color the Noble Gases purple.

Group 17: Halogens Named from Greek word meaning “forming salts”. These nonmetals are very reactive. They want to combine. They form compounds called “salts” They are so reactive, they can be used to kill living organisms. Chlorine is used to kill algae in pools. Iodine is used to kill bacteria in hospitals.

Halogens Color the Halogens Blue

Rare Earth Metals The top row of that bottom section is called the Rare Earth Metals. They were thought to be hard to find… hence, “Rare Earth Metals” Color the Rare Earth Metals green.

Alkali Metals Noble Gases Halogens Alkaline Earth Metals Transition Metals Rare Earth Metals

Radioactivity: What does it mean? Elements with isotopes (different numbers of neutrons in the nucleus) are unstable. An unstable nucleus can produce particles that shoot off from the nucleus. This causes a loss of protons and neutrons. Radioactivity- A loss of protons that causes the element to change into a different element!

Radioactive Elements (Period 7)

Size of atoms Atom size decreases Smallest! Size increases Fr Largest!

Which groups like to form ions? Form Negative Ions (Like to gain electrons) Form Positive Ions (Like to lose electrons) +1 +2 -5 -4 -3 -2 -1 Noble gases do not form ions!

We want to know the elements that are liquids at room temperature We want to know the elements that are liquids at room temperature. Make sure you know these 2 liquid elements! Bromine and Mercury Br Hg

H He N O F Ne Ar Cl Br Kr Xe Hg Rn Next, we want to know the elements that are gases at room temp. There are 11. H He N O F Ne Ar Cl Br Kr Xe Hg Rn
