Ra


​

Answer 1

Explanation:

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium ( Ca), strontium (Sr), barium (Ba), and radium ( Ra ...

Answer 2

The alkaline earth metal having the lowest ionization energy value is Barium

Alkaline earth metals are often named after their oxides.These oxides are basic when combined with water.

Explanation:

• Alkaline earth metals consists of Group 2 of the periodic table.Beryllium (Be),magnesium (Mg),calcium (Ca),Stroncium (Sr),barium (Ba) and Radium (Ra).
• These elements are shiny and silvery white metals.

• They are reactive metals at standard temperature and pressure
• Electropositive nature increases in size as we go down the group.
• Ionization energies decrease down the group.
• Ba is the most electropositive element
• Magnesium is the least in the electropositive element in the group.
• So correct order of electropositive nature is Mg>Ca>Sr>Ba
• The alkaline earth metal having the lowest ionization energy value is Barium
