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.
What else can I help you with?
How many valence electrons alkali metals have?
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.
Which group in the periodic table contain only metal?
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.
What can be found the right side of the periodic table?
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
The alkali metals have how many unpaired electrons?
Alkali metals, which are found in Group 1 of the periodic table, have one unpaired electron in their outermost shell. This single valence electron is responsible for their high reactivity, as it can easily be lost to form positive ions. The presence of one unpaired electron is a defining characteristic of alkali metals, leading to their distinct chemical behavior.
Which family in the periodic table contains the most reactive metals?
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.
How many valence electrons alkali metals have?
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.
Which group in the periodic table contain only metal?
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.
How many elements are classified as transition metals in the periodic table?
There are 38 elements classified as transition metals in the periodic table.
How many metals are on the periodic table?
Approx. 93 metals.
Where on the periodic table would you find metals and nonmetals?
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)"
How many non metals are there?
17 in periodic table

What can the vast majority of elements in the periodic table be classified as?
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.
How many non-metals in third period in the periodic table?
There are 4 non-metals in the third period of the periodic table (Phosphorous, sulfur, chlorine, and argon)
The alkali metals have how many unpaired electrons?
Alkali metals, which are found in Group 1 of the periodic table, have one unpaired electron in their outermost shell. This single valence electron is responsible for their high reactivity, as it can easily be lost to form positive ions. The presence of one unpaired electron is a defining characteristic of alkali metals, leading to their distinct chemical behavior.
How many types of elements on the periodic table of elements?
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
