Final answer:
The error in the Lewis dot diagram is: Another Cl should be shown around Mg that will receive the second electron on Mg.
The answer is option ⇒3
Step-by-step explanation:
In the given diagram, there is only one Cl atom shown around Mg, but Mg has two valence electrons. According to Lewis dot diagrams, each valence electron should be represented by a dot. Since Mg has two valence electrons, there should be another Cl atom shown around Mg to receive the second electron.
Therefore, the correct Lewis dot diagram should have two Cl atoms around Mg, each with seven dots (representing their valence electrons). One of the Cl atoms should transfer its unpaired electron to Mg, and the other Cl atom should receive the second electron from Mg.
By correcting this error, the Lewis dot diagram will accurately represent the compound and the sharing of electrons between Mg and Cl.
The answer is option ⇒3
Your question is incomplete, but most probably the full question was:
A student made the Lewis dot diagram of a compound as shown.
Mg is written with two dots shown on its top. Cl is written on the right side of Mg. Cl has seven dots around it. An arrow is shown from one dot on Mg toward the vacant space around Cl. Another arrow is shown from the other dot on Mg toward the vacant space around Cl. On the top, the art title is written as Students Lewis Dot Model.
What is the error in the Lewis dot diagram? (3 points)
- Another Cl should be shown around Mg that will transfer its unpaired electron to Mg.
- The number of dots around Mg should be one because there is only one Cl around Mg atom.
- Another Cl should be shown around Mg that will receive the second electron on Mg.
- The number of dots around Cl should be six because it is receiving two electrons from Mg.
