Final answer:
Tungsten has a higher density than chromium due to its greater mass per particle.
Step-by-step explanation:
The density of a substance is calculated by dividing its mass by its volume. In this case, we are comparing the density of chromium and tungsten. To make a prediction, we need to consider the mass of each metal. Given that the mass of a particle of chromium is 52 and the mass of a particle of tungsten is 184, we can conclude that tungsten has a higher density than chromium. This is because tungsten has a greater mass per particle, which means it will have a greater mass per unit volume, resulting in a higher density.
