Question

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

Answer 1

[AI-generated answer — Bot GPT 3.5]

The statement about the model that is correct is: The model should have 27 protons and 32 neutrons.

The atomic number of an element represents the number of protons in the nucleus, while the mass number represents the sum of protons and neutrons. In the case of cobalt, with an atomic number of 27 and a mass number of 59, the model should contain 27 protons (to match the atomic number) and 32 neutrons (59 - 27 = 32).
