- Metalloid
- Inert gas
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall the electronic configuration rule.
Elements that have 7 electrons in their outermost shell belong to Group 17 of the periodic table, known as the halogen group (e.g., Fluorine, Chlorine, Bromine, Iodine).
Step 2: Determine their properties.
These halogens are highly reactive non-metals. They gain one electron to achieve noble gas configuration, forming negative ions.
Step 3: Conclusion.
Thus, any element having 7 electrons in its outermost orbit is a non-metal.
