Alkali metals: Group 1 in the Periodic Table
Alkaline earth metals: Group 2
Halogens: Group 17
Noble Gases: Group 18
You can easily find them if you look at a periodic table.
Noble gases are unreactive.
Alkali metals (with one valence electrons) are more reactive than alkaline earth metals (with two valence electrons).
In the column nearest to the left hand side.
No. The alkali and alkaline earth metals are very reactive.
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.
It is located, in the periodic table, with the metalloids. However, it is a transition metal.
Alkaline earth metals do not exist , only alkali earth metals
Potassium is not an alkaline earth metal, it is an alkali metal. The metals in the leftmost column of the periodic table. They are noted for their high reactivity and for the fact that most of their compounds are basic.
I and II. The Alkaline Earth Metals and the Alkali Metals.
The Alkaline Earth Metals.
alkaline earth metals
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.
The alkali earth metals are in the 2nd group, or column of the Periodic Table. They are bordered by the alkali metals on the left and the transition metals on the right.
The alkali metals have a valence of 1 while the alkaline earth metals have a valence of 2. The alkali metals are generally lighter, softer, more reactive, and have lower melting points than the alkaline earth metals.
The alkali metals have a valence of 1 while the alkaline earth metals have a valence of 2. The alkali metals are generally lighter, softer, more reactive, and have lower melting points than the alkaline earth metals.
alkali metals
Metals are placed in group 1 (alkali metals) and group 2( alkaline earth metals) of the Periodic Table.
The group 1 is alled the alkali metals group.The group 2 is called the alkaline earth metals group.
They're metals that form alkaline compounds when they react with water.
