Yellowy-green
Colourless
Red
2
How many electrons does a full second electron shell have?
None of the above
2

3
Why does the reactivity of the alkali metals increase down the group?
The repulsion from the other electrons pushes they away
The pull from the nucleus is weaker on the outer shell
None of the above
They use more energy on the long orbits so have less to stay

Remain the same
Gain Electrons
11
