Barium (Ba) is the most electropositive element.
In general, electropositivity (reverse of electronegativity) decreases across the rows of the Periodic Table and increases down the columns.
Ca is more active because it has an atom that is large. The larger the distance the smaller the force. If you want more information you should visit Which_is_more_reactive_Mg_or_Ca_Why
Helium (He) is the element that has a negative electron affinity. This means that it is less likely to gain an electron compared to other elements listed (Kr, O, Ca, and Mg) which have positive electron affinities.
Strontium (Sr) would have properties similar to calcium (Ca) since they belong to the same group in the periodic table (Group 2) and have similar chemical behaviors. They both have two valence electrons and exhibit similar reactivity patterns.
Mg-24
In chemistry Ca stands for calcium and Mg stands for magnesium.
No. while magnesium is a very active element is is far from being the most active.

Mg (magnesium)

Ca is more active because it has an atom that is large. The larger the distance the smaller the force. If you want more information you should visit Which_is_more_reactive_Mg_or_Ca_Why
H2O. Notice the presence of two elements, H and O. Each of the other three is an element.
All the elements of Group 2 (Be, Mg, Ca, Sr, Ba, Ra)
Fluorine is the most active element due to its high electronegativity and small atomic size, making it eager to gain an electron to achieve a stable electronic configuration. This reactivity allows fluorine to readily form compounds with other elements.
