To determine which of the given elements will pair with a group 7 halogen like bromine (Br) in a 1:1 ratio based on the trends in valence electrons, we need to examine the valence electrons of each element.

1. Barium (Ba)
- Barium is in Group 2 of the periodic table.
- Elements in Group 2 have 2 valence electrons.

2. Aluminum (Al)
- Aluminum is in Group 13 of the periodic table.
- Elements in Group 13 have 3 valence electrons.

3. Potassium (K)
- Potassium is in Group 1 of the periodic table.
- Elements in Group 1 have 1 valence electron.

4. Sulfur (S)
- Sulfur is in Group 16 of the periodic table.
- Elements in Group 16 have 6 valence electrons.

Group 7 halogens, like bromine (Br), need 1 electron to complete their valence shell. Therefore, they tend to form a 1:1 ratio with elements that have exactly 1 valence electron.

Out of the given elements, potassium (K) has 1 valence electron. Thus, potassium will pair with bromine in a 1:1 ratio.

Therefore, the element that will pair with a group 7 halogen, such as bromine (Br), in a 1:1 ratio is:

Potassium (K).
