Question

bohr model quiz
draw the bohr model for the following elements.

1. mg⁺²
2. cl
3. ne

Explanation:

1. For $\text{Mg}^{2+}$: Magnesium has an atomic number of 12; the +2 charge means it lost 2 electrons, so it has 10 total electrons. The Bohr model has a nucleus labeled $\text{Mg}^{2+}$, with 2 electrons in the first energy level and 8 in the second.
2. For $\text{Cl}$: Chlorine has an atomic number of 17, so 17 electrons. The model has a nucleus labeled $\text{Cl}$, 2 electrons in the first level, 8 in the second, and 7 in the third.
3. For $\text{Ne}$: Neon has an atomic number of 10, so 10 electrons. The model has a nucleus labeled $\text{Ne}$, 2 electrons in the first energy level and 8 in the second.

Answer:

1. $\text{Mg}^{2+}$ Bohr Model:

• Nucleus: Labeled $\text{Mg}^{2+}$ (contains 12 protons, 12 neutrons)
• Energy Level 1: 2 electrons
• Energy Level 2: 8 electrons

1. $\text{Cl}$ Bohr Model:

• Nucleus: Labeled $\text{Cl}$ (contains 17 protons, 18 neutrons)
• Energy Level 1: 2 electrons
• Energy Level 2: 8 electrons
• Energy Level 3: 7 electrons

1. $\text{Ne}$ Bohr Model:

• Nucleus: Labeled $\text{Ne}$ (contains 10 protons, 10 neutrons)
• Energy Level 1: 2 electrons
• Energy Level 2: 8 electrons
