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

The model should show 27 protons and 27 neutrons.

The model should show 27 protons and 32 neutrons.

The model should show 59 protons and 27 neutrons.

The model should show 32 protons and 59 neutrons.

Answer 2

From Google:

While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is the key to the element's identity.

Answer 3

B. The model should show 27 protons and 32 neutrons, I think.

Answer 8

Question- Cobalt (Co) has an atomic mass of 59 and an atomic number of 27. Which statement correctly describes an atom of cobalt?
Answer- An atom of cobalt contains more neutrons than protons.

Answer 9

bruvv

Answer 10

the atomic number is the number of protons so 27 protons and 32 neutrons
(Yes I do know it was answered but just saying the atomic number is protons.)

Answer 11

m and kia are correct

Answer 12

Yes, you are correct. The atomic number of cobalt is 27, which represents the number of protons in the nucleus. The mass number of cobalt is 59, which represents the sum of protons and neutrons in the nucleus. Therefore, an atom of cobalt contains 27 protons and 32 neutrons.
