The periodic table grid shows F and K are in the same group, and D, E, F are in the same period. H, J, K, L are in the same period, and L is in the group to the right of K. If F and K are Halogens, wh

First, let's identify the elements based on their positions in the periodic table grid.
The grid shows:

• F and K are in the same group (column).
• D, E, F are in the same period (row).
• H, J, K, L are in the same period (row).
• L is in the group to the right of K, and in the same period as K.

From part (c)(i), the student correctly identified the group containing F and K as Halogens. This means F and K are in Group 17.

• F is in Period 3, Group 17: Chlorine (Cl)
