Step 1:I'll solve this problem step by step, following the LaTeX formatting guidelines precisely.
Step 2:: Determine the Atomic Number and Electron Configuration for Magnesium
- Magnesium's atomic number is 12 - This means magnesium has 12 protons in its nucleus - In a neutral atom, the number of protons equals the number of electrons
Step 3:: Calculate the Number of Neutrons
- $$24 - 12 = 12$$ neutrons
- Number of neutrons = Mass number - Atomic number
Step 4:: Electron Configuration
- Electrons are arranged in shells - First shell: 2 electrons - Second shell: 8 electrons - Third shell: 2 electrons - Total: 12 electrons
Step 5:: Draw the Bohr Model
- Nucleus at center with 12 protons and 12 neutrons - First shell (K shell): 2 electrons - Second shell (L shell): 8 electrons - Third shell (M shell): 2 electrons - Electrons arranged in concentric circles around nucleus
Final Answer
Bohr Model of Magnesium: - Protons: 12 - Neutrons: 12 - Electrons: 12 (2 - 8 - 2 configuration)
