How does the reactivity of L compare with that of F? Explain.

Here is the solution to question 3 from the image:

3) (c) How does the reactivity of L compare with that of F? Explain.

To compare the reactivity of L and F, we first need to understand their positions relative to each other in the periodic table.

• Element L is in the same period as F.
• Element L has one more proton than F, which means L is immediately to the right of F in the periodic table.

The trend in reactivity across a period depends on whether the elements are metals or non-metals:

• If F and L are metals: As you move from left to right across a period, the atomic radius decreases, and the ionization energy increases. This makes it harder for atoms to lose electrons.
