Question

fluorine belongs to group 17. how many covalent bonds are formed between two fluorine atoms?
○ 1
○ 3
○ 2
○ 4

Explanation:

Step1: Determine valence electrons of F

Fluorine (F) is in group 17, so it has 7 valence electrons. To achieve a stable octet (8 valence electrons), each F atom needs 1 more electron.

Step2: Analyze covalent bonding between two F

Two F atoms will share 1 pair of electrons (a single covalent bond) so that each atom has 8 valence electrons (7 + 1 from sharing). So, the number of covalent bonds between two F atoms is 1.

Answer:

1 (corresponding to the option "1")
