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
