Question

how many particles are in this diagram? 24 4 10

Explanation:

Step1: Count each group

• Orange: 10
• Blue: 6
• Gray: 2
• Red: 4

Step2: Sum all groups

$$10 + 6 + 2 + 4 = 22$$
But wait, check again. Wait, no - wait the problem is about particles. Each molecule (group of atoms) is a particle.

• Count each particle (group):
• Orange single: 1
• Orange pairs: 4 (each pair is 2 atoms but 1 particle), total orange particles: \(1+4 = 5\)
• Blue pairs: 3 (each pair is 1 particle), total blue particles: 3
• Gray pairs: 1 (1 particle)
• Red pairs: 2 (each pair is 1 particle)

Step3: Sum all particles

$$5+3 + 1+2=10$$

Answer:

10
