Question

1. the element with the electron configuration, (1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}), will have properties similar to...

a. manganese b. argon c. oxygen d. iodine

Explanation:

• Elements in the same group (column) of the periodic table have similar properties.
• The electron configuration \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}\) corresponds to chlorine (\(Cl\)).
• Chlorine (\(Cl\)) and iodine (\(I\)) are both in Group 17 (halogens).
• Manganese (\(Mn\)) is in Group 7, argon (\(Ar\)) is in Group 18, and oxygen (\(O\)) is in Group 16.

Answer:

d. iodine
