Solution
The correct explanation for why lithium is less reactive than sodium is:
"The outer electron in sodium is closer to the nucleus and is shielded by fewer inner shells of electrons. This means there is a stronger attraction between the positively charged nucleus and the negatively charged outer electron. This makes it harder for sodium to lose its outer electron compared to lithium."
This statement is incorrect. In reality, the outer electron in sodium is further from the nucleus and is shielded by more inner shells of electrons than lithium. This means there is a weaker attraction between the positively charged nucleus and the negatively charged outer electron in sodium. This makes it easier for sodium to lose its outer electron compared to lithium, making sodium more reactive.
The reactivity of alkali metals, such as lithium and sodium, increases down the group. This is because as you go down the group, the outermost electron is further from the nucleus and is shielded by more inner shells of electrons. This reduces the attraction between the nucleus and the outermost electron, making it easier for the atom to lose this electron and react.
