Metallic Character
Mediumchemistry
Which order shows increasing metallic character: B, C, N, O?
Select the correct option:
Solution
Incorrect! Answer:
O < N < C < B
- Metallic Definition: Tendency to lose electrons (electropositivity).
- Periodic Trend: Metallic character decreases from left to right across a period as ionization energy and electronegativity increase.
- Positions in Period 2:
- B (Group 13) - semi-metal/metalloid.
- C (Group 14) - non-metal.
- N (Group 15) - non-metal.
- O (Group 16) - non-metal.
- Relative scale: B is the most metallic in this set, and O is the least.
- Correct increasing order: O<N<C<B.
