To choose the correct option, we need to understand the concept of ionization energy and how it compares between alkali metals and alkaline earth metals.
Ionization energy is the energy required to remove an electron from an atom or ion in its gaseous state. It serves as a measure of how tightly the electrons are held by the nucleus.
Option c states that the first ionization energy of alkaline earth metals is more than that of corresponding alkali metals. This means that it is easier to remove an electron from an alkali metal than from an alkaline earth metal. This statement is true because alkali metals have only one electron in their valence shell, which is held less tightly compared to the electrons in the valence shell of alkaline earth metals.
Option d states that the first ionization energy of alkali earth metals is more than that of corresponding alkaline earth metals. This statement is incorrect because "alkali earth" metals is not a recognized term in chemistry.
Looking at these options, the correct option is c, "The first ionization energy of alkaline earth metals is more than that of corresponding alkali metals."
