Elements in Group 17 (column F) of the periodic table typically form how many single covalent bonds?

• A. 1
• B. 3
• C. 2
• D. 4

Answer: (A)

Verified step by step guidance

1. Identify the elements in Group 17 of the periodic table, also known as the halogens (e.g., fluorine, chlorine, bromine, iodine).
2. Recall that these elements have seven valence electrons, which means they need one more electron to complete their octet and achieve a stable electron configuration.
3. Understand that to complete their octet, Group 17 elements typically form one single covalent bond by sharing one electron with another atom.
4. Recognize that forming one single covalent bond allows these elements to have a full outer shell of eight electrons (octet rule).
5. Conclude that elements in Group 17 typically form 1 single covalent bond.
