They predominantly form ionic compounds
Option: 2
They have high ionisation enthalpy
Option: 3
They act as oxidising agent
Option: 4
All of the above
Answers (1)
The electronic configuration of Alkaline earth metals is: [noble gas] ns2
So, they have tendency to lose two valence electrons to attain stable noble gas configuration. Their ionisation enthalpy is low. They act as reducing agent.
The compounds of these elements are predominantly ionic except beryllium which forms covalent compounds due to anamalous behaviour.
