topic5 d4 assessment periodic table
12 of 42

1. which of the following elements is most likely to form a negatively charged ion?

o i
o br
o f
o cl

Explanation:

Step1: Consider electronegativity

Elements with high electronegativity tend to gain electrons and form negative ions.

Step2: Recall electronegativity trend

In the halogen group (Group 17), electronegativity decreases down the group. The order of electronegativity for the given halogens is \(F>Cl > Br>I\).

Answer:

F
