Question

part 4 (2 points) aluminum combined with chlorine is... formula: aici₃ name:

Explanation:

Step1: Determine ion charges

Aluminum (Al) has a +3 charge as it is in group 13 of the periodic - table and loses 3 electrons. Chlorine (Cl) has a -1 charge as it is in group 17 and gains 1 electron.

Step2: Balance charges

To balance the charges, we need 3 chlorine atoms for every 1 aluminum atom, resulting in the formula $AlCl_3$.

Step3: Name the compound

The compound $AlCl_3$ is named aluminum chloride.

Answer:

aluminum chloride
