A student has written the following answer to describe and explain the reactivity of group 1 metals. However, they've
made lots of mistakes. Can you correct them?
"As you go down group 1, reactivity decreases because it gets harder to gain an
Celectron lo the outer shell,
This is because as you go down group 1, the outer shell gets closer to the positive
nucleus, meaning that there is a weaker force of attraction between the nucleus
and the positive electrons on the inner shell,
There is also less electron shielding as you go down group 1, because there are
more inner shell electrons, which repel the outer shell electron,
All of these reasons mean that as you go down group 1 the outer shell electron is
harder to lose
