What would you expect to see when a piece of potassium is placed into a large bowl of water?
Floats, burns with a lilac flame and sparks
Sinks, no reaction
Floats, fizzes steadily and slowly becomes smaller
Why is sodium more reactive than lithium?
The outer electron is closer to the nucleus, so it is lost more easily
The outer electron is further from the nucleus, so it is harder to lose
The outer electron is further from the nucleus, so it is lost more easily
