Answer

Explanation:

Step1: Identify the atoms present using the provided key.

The key indicates that the blue sphere represents Carbon (C), the light blue spheres represent Hydrogen (H), and the red sphere represents Bromine (Br).

Step2: Count the number of each type of atom in the molecule model.

By observing the model, we can count:

  • 1 blue sphere (Carbon)
  • 3 light blue spheres (Hydrogen)
  • 1 red sphere (Bromine)

Step3: Write the chemical formula based on the atom counts.

The molecule contains 1 Carbon atom, 3 Hydrogen atoms, and 1 Bromine atom. Following the standard convention for writing chemical formulas (C first, then H, then other elements alphabetically), the formula is $CH_3Br$.

Answer:

$CH_3Br$
