Calcium has a larger atomic radius but less reactive than sodium. so why is sodium more reactive?

Can I please have explanation with references to the position of elements in the periodic table and trends in atomic radius and reactivity in the periodic table

Respuesta :

Sodium is more reactive than calcium because it has one electron in its outermost shell which means that its last shell is incomplete.

Why is sodium more reactive?

Sodium is more reactive than calcium atom because sodium has one outermost electron. Outermost electrons in sodium atom are less tightly held as a result sodium loses its outermost electron more easily and become stable element.

So we can conclude that Sodium is more reactive than calcium because it has one electron in its outermost shell which means that its last shell is incomplete.
