Presentation on theme: "Families on the Periodic Table"— Presentation transcript:
1 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.

5 Hydrogen Hydrogen belongs to a family of its own. Hydrogen is a reactive gas.Hydrogen was involved in the explosion of the Hindenberg.Hydrogen is promising as an alternative fuel source for automobiles
6 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
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 Elements in groups 3-12 Less reactive harder metals Includes metals used in jewelry and construction.Metals used “as metal.”
9 Boron Family Elements in group 13 Aluminum metal was once rare and expensive, not a “disposable metal.”
10 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.
11 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.
12 Oxygen Family or Chalcogens Elements in group 16Oxygen is necessary for respiration.Many things that stink, contain sulfur (rotten eggs, garlic, skunks,etc.)
13 Halogens Means salt former Elements in group 17 Very reactive, volatile, diatomic, nonmetalsAlways found combined with other elements in nature .Used as disinfectants and to strengthen teeth.
15 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.
