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.

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
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!
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.
Elements in group 2 are called?
Elements in group 2 are called alkaline earth metals. They include beryllium, magnesium, calcium, strontium, barium, and radium. They have two valence electrons and are relatively reactive.
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
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
Is alkaline earth metal in the group of metals nonmetals metalloids or diatomic molecule?
The alkaline earth metals are metals!
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Which alkaline earth metals are radioactive?
Radium is the radioactive metal among alkaline earth metals.
What is a globe or conductor or insulator?
A globe is a spherical representation of Earth or any other planet. A conductor is a material that allows the flow of electricity through it easily, such as metals. An insulator is a material that does not allow the flow of electricity through it easily, such as rubber or plastic.
What is the number of valence electrons in alkaline earth metals?
Alkaline earth metals have 2 valence electrons.
Which family is the element Radium in?
Radium is in the family of alkaline earth metals.
