Answer:

The answer to your question is: Fluorine, Chlorine, Bromine, Iodine

Step-by-step explanation:

Electron configuration ns² np⁵

We observe that this electron configuration finishes in "p". Elements from groups IIIA to VIIIA finish their electron configuration in "p".

Elements in Group IIIA finish in p¹

Group IVA finish in p²

Group VA finish in p³

Group VIA finish in p⁴

Group VIIA finish in p⁵

Group VIIIA finish in p⁶

Then, the list of elements with this electron configuration is:

Fluorine, Chlorine, Bromine, Iodine
