Why is rubidium more reactive than potassium?

the outer electron of a rubidium atom is further from the nucleus than potassium's

the metallic bonds in rubidium are weaker than those in potassium

rubidium has a more exothermic reaction with water than potassium does

rubidium is a softer metal than potassium

This question is about gases.
When sodium is added to water, hydrogen gas is produced.
Which observation shows that a gas has been produced?

a white precipitate forms

Lithium, sodium and potassium are reactive metals in group 1 of the periodic table.
In an experiment equal-sized pieces of lithium, sodium and potassium are added to separate
samples of water.
A flame is produced only with potassium because potassium

has the lowest melting point

is the softest metal

is the only flammable metal

is the most reactive

6 / 10

Which statement explains why Group 1 metals get more reactive further down the group?

There is an increasing attraction between the outer electron and nucleus

The outer electron is closer to the nucleus and harder to lose

There is a decreasing attraction between the outer electron and nucleus so the electron is more easily lost

There is less shielding of the outer electron so it is easier to lose

7 / 10

It contains an ionic compound

It contains water

It contains hydroxide ions

Hydrogen gas is made
