Cobalt has a mass of 59 and a atomic number of 27A student wants to create a model of a cobalt atom which statement about the model is correct
SHUT UP DRBOB222
To create a model of a cobalt atom, you need to understand its basic structure. Cobalt has a mass of 59 and an atomic number of 27. Here's how you can use this information to determine the correct statement about the model:
1. Protons and Neutrons: The atomic number of cobalt, 27, represents the number of protons in its nucleus. Since protons have a mass of approximately 1 atomic mass unit (amu), cobalt has 27 protons. The mass of cobalt is given as 59, which means it has 59 - 27 = 32 neutrons. Therefore, the nucleus of the cobalt atom contains 27 protons and 32 neutrons.
2. Electrons: In a neutral atom, the number of electrons is equal to the number of protons. Since cobalt has 27 protons, it also has 27 electrons surrounding the nucleus.
3. Electron Configuration: Cobalt's electron configuration can be determined using the periodic table. It has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁷. This means that in its ground state, cobalt has two electrons in the 1s orbital, two electrons in the 2s orbital, six electrons in the 2p orbital, two electrons in the 3s orbital, six electrons in the 3p orbital, two electrons in the 4s orbital, and seven electrons in the 3d orbital.
Based on this information, the correct statement about the model of a cobalt atom is: The model of a cobalt atom should depict a nucleus with 27 protons and 32 neutrons, and it should also show 27 electrons orbiting the nucleus. The electron configuration should indicate the distribution of electrons among the various energy levels and orbitals.
The correct statement about the model of a cobalt atom is:
- The model should include 27 protons, 27 electrons, and 32 neutrons.
