Why alkali metals do not show 2 oxidation state?
Because they have only one electron in their valency shell. The second oxidation state would require the atom to lose an electron from its penultimate shell which is full.
What is the group number of alkali earth metals?
Alkali earth metals are placed in the second group of the periodic table of Mendeleev.
Are alkali metals the first or second group?
First group
Where are the alkali metals and the halogens located on the periodic table?
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
What do alkali metals react vigorously with?
An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.

What are the elements called in the first group of the periodic table that have one outer shell electron and is extremely reactive?
The elements in the first group of the period table which have one electron in their outer shells and react extremely well are also known as the alkali metals. These elements are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.

What is alkali metals and alkali earth metals?
Alkali metals are in the first column of the periodic table, but do not include Hydrogen. The alkali metal family is composed of Lithium, Sodium, Potassium, Rubidium, Cesium and Francium. An example of an alkali metal is Sodium (Na).
Why transition metals are different than the alkali and alkali earth?
it is because transition metals falls under differen group in the period table. Alkali elements falls in frirst group alkali earth metal falls in second group and the followed by groups are transition elemets
What is in the second column of the periodic table?
Alkaline earth metals are placed in second column. The elements have 2 valence electrons.
What groups are alkaline earth metals and the alkali metals in?
the first and second groups. alkaline earth metals: group IIA (2) [It consists with "Be,Mg,Ca,Sr,Ba,Ra"] alkali metals: group IA (1) [It consists with "Li,Na,K,Rb,Cs,Fr"]
What groups are alkaline earth metals and alkali metals in?
the first and second groups. alkaline earth metals: group IIA (2) [It consists with "Be,Mg,Ca,Sr,Ba,Ra"] alkali metals: group IA (1) [It consists with "Li,Na,K,Rb,Cs,Fr"]
Where is the earth metals on periodic table?
Do you mean Alkali Earth metals? If so they are the second column to the left of the chart.http://www.elementsdatabase.com/Images/periodic_table1.gif
