Question

Alkaline earth metals

• A. form predominantly ionic compounds
• B. Covalent
• C. Oxidising agent
• D. All of the above

Answer 1

The correct option is A form predominantly ionic compounds

The electronic configuartion of Alkaline earth metals is: [noble gas] $n{s}^2$

So, they have tendency to loose valence electrons. The compounds of these elements are predominantly ionic. Except berrylium which forms covalent compounds due to anamalous behaviour.
