Question

consider the elements below. rank them from lowest to highest attractive forces based on their state of matter. mg (solid), h2 (gas), br2 (liquid) mg, h2, br2 h2, br2, mg mg, br2, h2

Explanation:

Step1: Recall states - matter and forces

In gases, particles are far apart, so attractive forces are weakest. In liquids, particles are closer, with stronger forces than gases. In solids, particles are closely - packed, having the strongest attractive forces.

Step2: Identify states of given substances

$H_2$ is a gas, $Br_2$ is a liquid, and $Mg$ is a solid.

Step3: Rank based on forces

Based on the above, the order from lowest to highest attractive forces is gas ($H_2$), liquid ($Br_2$), solid ($Mg$).

Answer:

$H_2$, $Br_2$, $Mg$
