Halogens are found in which group on the periodic table?

Group 15
Group 17
Group 1
Group 8

The correct answer is: Group 17

Halogens (fluorine, chlorine, bromine, iodine, and astatine) are found in group 17 on the periodic table. Group 15 (nitrogen group) contains elements like nitrogen, phosphorus, arsenic, and antimony which are not halogens. Group 1 (alkali metals) contains elements like lithium, sodium, and potassium which are not halogens either. Group 8 (noble gases) contains elements like helium, neon, and argon which are also not halogens. Therefore, the only correct answer is option B.
