Question

sketching atoms using the bohr model sketch the following atoms, placing all electrons in the correct principal quantum numbers. indicate the number of protons, neutrons, and electrons. 1. h 2. he 3. li 4. al 5. c 6. ne

Explanation:

Step1: Determine for Hydrogen (H)

Hydrogen has atomic number 1. Protons = 1, electrons = 1. For most common isotope, neutrons = 0. In Bohr - model, 1 electron in n = 1 shell.

Step2: Determine for Helium (He)

Helium has atomic number 2. Protons = 2, electrons = 2. Most common isotope has neutrons = 2. 2 electrons in n = 1 shell.

Step3: Determine for Lithium (Li)

Lithium has atomic number 3. Protons = 3, electrons = 3. Most common isotope has neutrons = 4. 2 electrons in n = 1 shell, 1 electron in n = 2 shell.

Step4: Determine for Aluminum (Al)

Aluminum has atomic number 13. Protons = 13, electrons = 13. Most common isotope has neutrons = 14. 2 electrons in n = 1 shell, 8 electrons in n = 2 shell, 3 electrons in n = 3 shell.

Step5: Determine for Carbon (C)

Carbon has atomic number 6. Protons = 6, electrons = 6. Most common isotope has neutrons = 6. 2 electrons in n = 1 shell, 4 electrons in n = 2 shell.

Step6: Determine for Neon (Ne)

Neon has atomic number 10. Protons = 10, electrons = 10. Most common isotope has neutrons = 10. 2 electrons in n = 1 shell, 8 electrons in n = 2 shell.

Answer:

Atom	Protons	Neutrons	Electrons	Electron Distribution in Bohr - model
He	2	2	2	2 in n = 1
Li	3	4	3	2 in n = 1, 1 in n = 2
Al	13	14	13	2 in n = 1, 8 in n = 2, 3 in n = 3
C	6	6	6	2 in n = 1, 4 in n = 2
Ne	10	10	10	2 in n = 1, 8 in n = 2
