Halogens are located in which position on the periodic table?

• A. Rightmost column
• B. Second from right
• C. Leftmost column
• D. Center

Answer: (B)

The key idea is how the periodic table is organized by valence electrons in each column. Halogens have seven valence electrons and therefore sit in the column just before the noble gases, which already have a full octet. In the standard layout, the noble gases occupy the rightmost column, so the halogens are in the second-from-right column. This placement reflects their shared need for one more electron to complete the octet, and it groups them with other highly reactive nonmetals in the same column.

So, halogens are in the second-from-right column, not the rightmost column (noble gases), not the leftmost column (alkali metals), and not the center (transition metals).
