when sodium, potassium and lithium are put into water they all react vigourously giving off hydrogen gas and turning the water alkaline. explain why the reactions of these metals are important in placing them within the periodic table.

Because it shows how reactive the elements are

they react vigorously since they only need to lose 1 electron to have a full outer shell

the groups of elements are based on number of electrons in the outer shell, so these elements are all in group 1

They are all grouped together because they are highly reactive with water.

They are important, as they are listed in reactivity order in Group 1 of the periodic table.

The group 1 elements become more reactive as you go down the group. At the top, lithium is the least reactive and francium at the bottom is the most reactive.

so "the reaction of those metals are important as it shows how reactive they are", is that a good answer?

The reactions of the metals are important as they show us how reactive each metal is and therefore they can be accurately be placed in order of reactivity in the periodic table.

^ That's a good answer to write.

Yeah.

The reactions of the metals in water are important as they show us how reactive each metal is and therefore they can be accurately be placed in order of reactivity in the periodic table.

Use my answer ^

Hope I helped, science is fun!
