Cobalt has a mass number of 59 and an atomic number of 27 a student wants to create a model of a cobalt atom which statement about the model is correct A The model should show 32 protons in 59 neutrons B The model should show 59 protons in 27 neutrons C The model should show 27 protons and 32 neutrons D The model should show 27 protons and 27 neutrons

The correct statement about the model of a cobalt atom is:

C: The model should show 27 protons and 32 neutrons.

Here's the breakdown:

• The atomic number of cobalt is 27, which means it has 27 protons.
• The mass number of cobalt is 59, which is the total number of protons and neutrons in the nucleus.

To find the number of neutrons, you subtract the number of protons from the mass number:

Number of neutrons = Mass number - Number of protons Number of neutrons = 59 - 27 = 32

So, a cobalt atom has 27 protons and 32 neutrons.
