Group 1 Alkali Metals (lithium, sodium and potassium)

How do all the metals in group 1 react with water?

They react vigorously to create an alkaline solution and hydrogen

How many electrons do group 1 elements have in their outer shell?

they have 1 electron

What do these elements make with oxygen?

an oxide

What does it mean if a group 1 element has more bubbles when it reacts to water?

it’s a more reactive alkaline metal because it has a more vigorous reaction

What happens to the reactiveness as you go down group 1?

Reactivity increases - ( e.g. from lithium to potassium) and it applies for any reaction

What’s the reaction of lithium and water like?

It fizzes steadily, because it is not too reactive

What’s the reaction of sodium and water like?

melts into a ball then fizzes quickly

What’s the reaction of potassium and water like?

gives off sparks and hydrogen burns with lilac flames

What are electronic configurations?

How an atoms electrons are arranged in shells

Why is it easier for atoms to lose electrons as you go further down the group?

Atoms get more electron shells, which increases shielding. This weakens the attraction between the nucleus and the outer electrons, so they are lost more easily
