Question

use the periodic table to select the element from the drop - down menu that has the correct relative electronegativity. mg > p > c < br < done

Explanation:

Step1: Recall electronegativity trends

Electronegativity increases across a period and decreases down a group on the periodic table.

Step2: Analyze Mg comparison

Magnesium (Mg) is a metal. Elements to the right of Mg in the same period have higher electronegativity. For example, Al has higher electronegativity than Mg.

Step3: Analyze P comparison

Phosphorus (P) is a non - metal. Elements to the right of P in the same period have higher electronegativity. For example, S has higher electronegativity than P.

Step4: Analyze C comparison

Carbon (C) is a non - metal. Elements to the left of C in the same period have lower electronegativity. For example, B has lower electronegativity than C.

Step5: Analyze Br comparison

Bromine (Br) is a non - metal. Elements to the right of Br in the same period have higher electronegativity. For example, Cl has higher electronegativity than Br.

Answer:

For Mg, possible answers could be elements like Al (if options include it). For P, possible answers could be elements like S. For C, possible answers could be elements like B. For Br, possible answers could be elements like Cl. (Since no specific options are given, this is a general guide based on electronegativity trends).
