M4 The Periodic Table: Group 1 & 2 metals

Slide 36 of 42

Reactivity of Group 2 and 3 Metals

Since calcium reacts with water while magnesium requires steam, calcium is more reactive than magnesium.

In other words, reactivity increases going down group 2 as well just as with group 1 metals for the same reason.

Therefore, going Down Group 2

EASIER to LOSE OUTER ELECTRON

So MORE CHEMICALLY REACTIVE

That is, it is easier for Ba to lose two electrons than it is for Ca.

And it is easier for Ca to lose two electrons than it is for Mg etc.
