1 Hydrogen Nonmetal! Exists as H 2 (diatomic) when alone as an element. Most abundant element in universe… Rare in Earth’s atmosphere Click here for hydrogen demo

2 Alkali Metals Group 1 (1A) Properties of all metals… Shiny & Good Conductors Malleable – can be hammered into thin sheets. Ductile – can be drawn into thin wires. [http://wps.prenhall.com/wps/media/objects/602/616516/Media_ Assets/Chapter01/Text_Images/FG01_02-04UN.JPG]

3 Alkali Metals Low density and melting points. Soft and silver-white in color Highly unstable elements that are not found pure in nature. [http://www.microchem.de/elec000a-k.JPG]

4 Alkali Metals All form +1 ions. Most reactive metals on table (low ionization energy) and this increases from Li to Fr. Click here for Alkali Metals & Water Demos [http://wps.prenhall.com/wps/media/objects/476/4883 16/Instructor_Resources/Chapter_09/FG09_33.JPG]

5 Alkaline Earth Metals Group 2A Higher density and M.P. than Alkali Metals. [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter01/Text_Images/FG01_02-04UN.JPG]

6 Alkaline Earth vs. Alkali Metals [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter06/Text_Images/FG06_TB05.JPG]

7 Alkaline Earth Metals More of a silver-metallic color for this group. Also highly reactive in nature, but can be stored as an element. [http://www.chemsoc.org/viselements/pa ges/data/graphic/ca_data.jpg]

8 Alkaline Earth Metals All form +2 ions. [http://wps.prenhall.com/wps/media/objects/476/4883 16/Instructor_Resources/Chapter_09/FG09_34.JPG] Click here for videos on the Alkaline Earth Metals

9 p-Block Groups Groups 13-16 named after the first element. Boron Group 13 (3A) +3 ions

10 [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter19/Text_Images/FG19_TB03.JPG]

11 p-Block Groups Carbon Group 14 (4A) No ion pattern because all have 4 valence electrons [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter19/Text_Images/FG19_02-09UN.JPG]

12 p-Block Groups Nitrogen Group (-3 ions) Oxygen Group (-2 ions) [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter19/Text_Images/FG19_02-09UN.JPG]

13 p-Block Groups Both Nitrogen and Oxygen are diatomic as elements (N 2 & O 2 )

14 Halogens Group 17 (7A) Some are diatomic when alone as an element. [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter01/Text_Images/FG01_02-04UN.JPG]

15 The “Super Seven” are all diatomic when alone as elements!

16 Halogens Exist as gas, liquids, and solids with distinct colors.

17 Halogens Most reactive non-metals on table and increases from I To F. All form –1 ions. Most form salts by combining with alkali metals. (+1 ion with –1 ion) Click here for Halogen reactivity video Click here for videos on the Halogens
