the ionization energy for calcium and magnesium is shown below,Does there seem to be a correlation between reaction rate and ionization energy?explain

__________Ionization Energy(kj/mol)
Element_____First_______Second

Calcium_____590________1146
magnesium__738________1450

explain

____________this line is just a space

Both atoms, calcium and magnesium, become stable by losing both of their 2 valence electrons. Because calcium's 2 valence electrons are in the 4th energy level (the 4s sublevel) as compared to magnesium's 3rd energy level for the valence shell, calcium's electrons are easier to remove because of their increased distance from the attracting nucleus.

Calcium ease of losing electrons (ionizing) makes it more reactive than magnesium. Generally we can predict that the lower the ionization energies, the more reactive a metallic element is.
