6: lithium(Li) ,sodium(Na) , potassium(K) , rubidium (Rb) , cesium (Cs) and Francium(Fr).
Practically,only the first five can be termed alkali metals,because there is not enough Francium in the planet to examine its characteristics. Of course, the electron structure of the atom of Francium "proposes" an alkali metal.
alkali metals have 1 electron in there outer valence shell. I remember that alkali and alkaline go with columns 1 & 2 of the periodic table alphabetically. Alkali then alkaline. Alkali metals have 1 valence electron. Alkaline metals have 2 valence electrons.
There are many groups in the periodic table that only contain metals. There are the Alkali metals, the Alkaline earth metals, Lanthanoids, Actinoids, Transition metals, and the Post-transition metals.
The periodic table consists on many different elements. on the right there is the Non-metals, and on the left and middle are the metals. to find out what all of these elements are copy and paste this into the browser;http://www.youtube.com/watch?v=GFIvXVMbII0
Apart from Hydrogen, Helium and Beryllium; non metals are located in the p-block. Starting from the third period with addition of Li, all of s-block elements are metals. The d-block elements are a compete set of metals.
Group 1 on the periodic table, also known as the alkali metals group, contains 6 elements: hydrogen, lithium, sodium, potassium, rubidium, and cesium. It is located on the far left side of the periodic table.
alkali metals have 1 electron in there outer valence shell. I remember that alkali and alkaline go with columns 1 & 2 of the periodic table alphabetically. Alkali then alkaline. Alkali metals have 1 valence electron. Alkaline metals have 2 valence electrons.
There are many groups in the periodic table that only contain metals. There are the Alkali metals, the Alkaline earth metals, Lanthanoids, Actinoids, Transition metals, and the Post-transition metals.
Approx. 93 metals.
There are 38 elements classified as transition metals in the periodic table.
The metalloids split the table these are a diagonal group of elements, B, Si, Ge, As, Sb and Te. To their right are the non metals to the left the metals. There are many more metals than any other type of element. See Wikipedia article "Periodic table (metals and non metals)"

The vast majority of elements in the periodic table can be classified as metals. Metals make up the s-block, d-block, and f-block of the periodic table. There are even a few elements in the p-block with metallic properties called metalloids.
There are 4 non-metals in the third period of the periodic table (Phosphorous, sulfur, chlorine, and argon)
a lot of a lot
I think there are 76
On the Periodic Table there are the following Groups: Group 1 - Alkali Metals Group 2 - Alkaline Earth Metals Transition Metals - Including Lanthanides and Actinides Post Transition Metals Metalloids Other Non Metals Group 7 - Halogens Group 0 - Inert Gases
