Ok this question is a little tricky question. Let us answer this question based on concept of band theory. let us look at group 1 metals. Take the example of Na. It has only one valance electron. Hence the band diagram will be incomplete when sketched and due to this the nature of the element that is Na is metallic and also it exhibits good conductivity.
Now let us take the case of group 2 metals. Since the valence electron will be two and both of them will be filled, there will be an overlap of band. This will give it metallic nature but on the contrary since there will not be empty states it will be a poor conductor when compared to group 1.
Note: Group 2 metals exhibit conductivity but on a comparative scale with group 1 and 3 they are bad conductors.

a. each is a good conductor of electricity b. they are never found uncombined in nature c. they lose two electrons in chemical reactions
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
The alkaline earth metals are found in group?
The alkaline earth metals are in the group 2 of the periodic table of Mendeleev.
Compare and contrast the reaction of alkaline earth metals with their salts?
All alkaline earth metals and their salts are reactive and they have a blue-print that identifies them as an alkaline earth metal but metals exist as metals, and salts as salts, with different structural compounds.
What arethree alkaline-earth metals besides calcium?
Beryllium, magnesium and barium are three more alkaline earth metals.
Do alkaline earth metals conduct electricity and heat?
yes, all metals do!
What is group 2A elements known as?
Alkaline Earth Metals
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
Is radon an conductor of heat?
The radioactive element radium is a pretty good conductor of thermal and electrical energy. We see radium at the bottom of the Group 2 elements, the Alkaline Earth Metals. It can conduct heat and electricity well.
Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
What are Group 2 called?
Alkaline Earth Metals
Circle the letter of each sentence that is true about alkaline earth metals?
a. each is a good conductor of electricity b. they are never found uncombined in nature c. they lose two electrons in chemical reactions
What is the group of alkaline earth metals?
Group 2 contains the alkaline earth metals
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
What is the name of the 2nd group in the periodic table?
Group 2 is the Alkaline Earth Metals. A link can be found below.
Is alkaline earth metal in the group of metals nonmetals metalloids or diatomic molecule?
The alkaline earth metals are metals!
Why are group 2 metals classified as alkaline earth metals?
as most of the metals of group 2 are found in earth soil in large amount and they are alkaline metals. This is the main reason for calling alkaline earth metals.
