Presentation on theme: "Coloring the Periodic Table Families"— Presentation transcript:
1 Coloring the Periodic Table Families You need 11 different colors
2 Families on the Periodic Table Elements on the periodic table can be grouped into families bases on their chemical properties.Each family has a specific name to differentiate it from the other families in the periodic table.Elements in each familyreact differently withother elements.The horizontal rows arecalled periods and arelabeled from 1 to 7.The vertical columns are called groups or families and are labeled from 1 to 18.
3 Hydrogen Hydrogen belongs to a family of its own. Hydrogen is a diatomic, reactive gas.Hydrogen was involved in the explosion of the Hindenberg.Hydrogen is promising as an alternative fuel source for automobilescolor hydrogen color 1
4 ALKALI METALS Group 1 Hydrogen is not a member, it is a non-metal 1 electron in the outer shellSoft and silvery metalsVery reactive, esp. with waterConduct electricityColor the rest of this group color 2
5 Alkali Metals1st column on the periodic table (Group 1) not including hydrogen.Very reactive metals, always combined with something else in nature (like in salt).Soft enough to cut with a butter knife
6 ALKALINE EARTH METALS Group 2 2 electrons in the outer shell White and malleableReactive, but less than Alkali metalsConduct electricityColor the Alkaline Earth Metals color 3
7 Alkaline Earth Metals Second column on the periodic table. (Group 2) Reactive metals that are always combined with nonmetals in nature.Several of these elements are important mineral nutrients (such as Mg and Ca
8 TRANSITION METALS Groups 3-12 Good conductors of heat and electricity. Some are used for jewelry.The transition metals are able to put up to 32 electrons in their second to last shell.Can bond with many elements in a variety of shapes.Color Transition Metals color 4
9 Transition Metals Elements in groups 3-12 Less reactive harder metals Includes metals used in jewelry and construction.Metals used “as metal.”
10 BORON FAMILY Group 13 3 electrons in the outer shell Most are metals Boron is a metalloidColor Boron Family color 5
11 Boron Family Elements in group 13 Aluminum metal was once rare and expensive, not a “disposable metal.”
12 CARBON FAMILY Group 14 4 electrons in the outer shell Contains metals, metalloids, and a non-metal Carbon (C)Color Carbon Family with color 6
13 Carbon Family Elements in group 14 Contains elements important to life and computers.Carbon is the basis for an entire branch of chemistry.Silicon and Germanium are important semiconductors.
14 NITROGEN FAMILY Group 15 5 electrons in the outer shell Can share electrons to form compoundsContains metals, metalloids, and non-metalsColor the nitrogen family with color 7
15 Nitrogen Family Elements in group 15 Nitrogen makes up over ¾ of the atmosphere.Nitrogen and phosphorus are both important in living things.Most of the world’s nitrogen is not available to living things.The red stuff on the tip of matches is phosphorus.
16 OXYGEN FAMILY or Chalcogens Group 166 electrons in the outer shellContains metals, metalloids, and non-metalsReactiveColor the Oxygen family with color 8
17 Oxygen Family or Chalcogens Elements in group 16Oxygen is necessary for respiration.Many things that stink, contain sulfur (rotten eggs, garlic, skunks,etc.)
18 Halogens Group 17 7 electrons in the outer shell All are non-metals Very reactive are often bonded with elements from Group 1Color the Halogen group with color 9
19 Halogens Elements in group 17 Very reactive, volatile, diatomic, nonmetalsAlways found combined with other element in nature .Used as disinfectants and to strengthen teeth.
20 Noble Gases Group 18 Exist as gases Non-metals 8 electrons in the outer shell = FullHelium (He) has only 2 electrons in the outer shell = FullNot reactive with other elementsColor the noble gases with color 10
21 The Noble Gases Elements in group 18 VERY unreactive, monatomic gases Used in lighted “neon” signsUsed in blimps to fix the Hindenberg problem.Have a full valence shell.
22 Rare Earth Metals Some are Radioactive The rare earths are silver, silvery-white, or gray metals.Conduct electricityColor Rare Earth Metals with color 11
