Question

22 multiple choice 1 point
which color has the smallest bonding atomic radii?
○ green
○ yellow
○ red
○ orange

Explanation:

Step1: Recall Atomic Radius Trend

Atomic radius decreases across a period (left to right) and increases down a group (top to bottom) in the periodic table.

Step2: Identify Positions of Colors

• Green: Likely in Group 1 (alkali metals), upper left.
• Yellow: Lower right, maybe Group 17 or 16, lower period.
• Red: Middle - d - block, middle period.
• Orange: Upper right, likely Group 17 or 18, upper period (near noble gases or halogens in upper rows).

Step3: Compare Based on Trend

To have the smallest atomic radius, the atom should be in the upper - most and right - most position (since radius decreases right across a period and up a group). Orange is in the upper right, closer to the top and right compared to others. Green is upper left (large radius for its period), yellow is lower (larger due to lower period), red is middle (larger than upper right elements). So orange has the smallest bonding atomic radius.

Answer:

D. orange (assuming options are A. green, B. yellow, C. red, D. orange as per the order and the correct one is orange)
