The atomic number of cadium is half the atomic number of curium. Define a variable and write an expression for the atomic number of cadmium. I'm working in a group with my friends and we need help we're not the same people.

To define a variable for the atomic number of cadmium, let's call it "Cd_atomic_number."

Since the atomic number of cadmium is half the atomic number of curium, we can express it as:

Cd_atomic_number = 1/2 * Cm_atomic_number

Here, "Cm_atomic_number" represents the atomic number of curium. By multiplying it by 1/2, we obtain half of the atomic number, which corresponds to the atomic number of cadmium.
