Question

Chemical Properties of group II elements​

Answer 1

• Relatively reactive, but less than high reactive alkali metals
• Forms halides when reacted with halogens
• Forms oxides when reacting with air, leading to a dull appearance in pure form
• Form +2 charge in cationic form
• Form ionic bonds with other negatively charged ionic form of elements
• Examples:
  `CaCO_(3)` Calcium carbonate aka chalk,
  `Sr(NO_(3))_(2)` Strontium nitrate.
