All alkaline earth metals loss two electrons.
2 electrons on their outershell. They're all Metals, they all exhibit Metallic Bonding.
A metalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. They are electrical semiconductors.
They are highly reactive and form ionic bonds.
2 valence electrons (apex)
No. The alkali and alkaline earth metals are very reactive.
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
The alkaline earth metals are in the group 2 of the periodic table of Mendeleev.
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.
All alkaline earth metals loss two electrons.

All of the alkaline earth metals are naturally occurring and they share similar properties: they are all rather reactive metals under standard conditions.
The alkaline earth metals and especially barium.
they are harder than alkali metals
highly reactive with alkali metals and alkaline earth metals
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.
Alkaline Earth Metals
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.
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
