part a\nan element from group 13 bonds with an element from group 17. which formula correctly depicts the correct chemical formula for elements from these two groups?\na alcl₃\nb b₃i\nc bf\nd brga₃

Answer

Explanation:

Step1: Determine valences

Elements in Group 13 have a +3 valence (they tend to lose 3 electrons), and elements in Group 17 have a - 1 valence (they tend to gain 1 electron).

Step2: Apply valence - to - formula rule

To form a neutral compound, the total positive charge must equal the total negative charge. So, for a compound between a Group 13 and a Group 17 element, we need 3 Group 17 atoms for every 1 Group 13 atom.

Answer:

A. $\ce{AlCl3}$
