Question:
The atomic number of fluorine is 9. Explain the formation of the fluorine molecule (F₂). [Pg. No. 170]
Answer:
Verified
Fluorine has atomic number 9, so its electronic configuration is 2, 7. Therefore, each fluorine atom has 7 valence electrons and needs 1 more electron to complete its octet. Two fluorine atoms share one electron each and form a single covalent bond. In this way, both atoms complete their outermost shell and form a stable fluorine molecule (F₂).
