Verified step by step guidance1
Recall that the halogen family is Group 17 (VIIA) on the periodic table, which includes elements known for their high reactivity and seven valence electrons.
Identify the elements given in the problem: Ne (Neon), Mg (Magnesium), and K (Potassium).
Determine the group of each element: Ne is a noble gas in Group 18, Mg is an alkaline earth metal in Group 2, and K is an alkali metal in Group 1.
Since none of the listed elements (Ne, Mg, K) belong to Group 17, recognize that the correct halogen element mentioned is Cl (Chlorine), which is indeed in Group 17.
Conclude that Cl is the correct answer because it is a member of the halogen family, characterized by its position in Group 17 of the periodic table.
