All of the members of the alkali metal family have one valence electron (in their outermost s orbital). Therefore, they are strong reducing agents and tend to react in such a way as to lose this electron in order to obtain a more stable electron configuration.
Alkali metals are metallic, and therefore all have a Silvery-grey appearance.
(Alkali metals are stored usually in oil, and when they are removed from the oil they usually have a dull grey colour because of the minor reaction that the metal has with the oil. Only the outer most part of the alkali metal will be this colour, and when cut, the middle of the metal will be exposed, and the silvery-grey appearance can be observed.)
All the alkali metals behave in similar way because they are all in a same group.
All alkaline earth metals loss two electrons.
All alkaline earth metals loss two electrons.
Group 2 elements in the periodic table are the alkaline earth metals.
b. valence electrons d. electrons needed to fill their octet
All of the alkaline earth metals are naturally occurring and they share similar properties: they are all rather reactive metals under standard conditions.
Group 2A elements are commonly known as the alkaline earth metals, while groups 1A is called the alkali metals.
2 valence electrons (apex)
All alkaline earth metals loss two electrons.
Group 2 elements in the periodic table are the alkaline earth metals.
No,but group 2 are alkaline earth elements
Astatine is a heavy halogen; no similarities with strontium (alkaline earth metal).
Alkaline-earth elements form cations.

All alkaline Earth metals have tow valence electrons in their last orbit(Valency is +2) and hence have similar properties. So, they are placed in the same group.
The elements of the second group are called the Alkaline Earth metals.
there are 6 elements
