Hydrogen
Nonmetal! Exists as H2 (diatomic)
when alone as an element.
Most abundant element in universe…
Rare in Earth’s atmosphere

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.

Alkali Metals Low density and
melting points. Soft and silver-white
in color Highly unstable
elements that are not found pure in nature.

Alkali Metals
All form +1 ions. Most reactive metals on
table (low ionization energy) and this increases from Li to Fr.

Alkaline Earth Metals
Group 2A Higher density
and M.P. than Alkali Metals.

Alkaline Earth vs. Alkali Metals
[http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter06/Text_Images/FG06_TB05.JPG]
Alkaline Earth Metals
More of a silver-metallic color for this group.
Also highly reactive in nature, but can be stored as an element.

Alkaline Earth Metals
All form +2 ions.

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

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]
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]
p-Block Groups
Both Nitrogen and Oxygen are diatomic as elements (N2 & O2)
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]
The “Super Seven” are all diatomic when alone as
elements!
Halogens
Exist as gas, liquids, and solids with distinct colors.
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)
