Question

bohr model of the atom
element: oxygen

of protons (+): ______________ (equal to the atomic number of the element.)

of electrons (-): ____________ (equal to the number of protons in a neutral atom.)

of neutrons: ______________ (equal to the atomic mass minus the atomic number.)

using the periodic table provided, complete the element box & above questions.
using the step - by - step guide for bohr models, complete the blank model below.
bohr model diagram with circles for electron shells, and a central circle with p⁺ (protons) and n (neutrons) labels, with blanks to fill in the number of protons and neutrons, and electron shells to fill with electrons

Explanation:

Step1: Find Oxygen's atomic number

From the periodic table, oxygen (O) has an atomic number of 8. This equals the number of protons.

Step2: Determine electron count

For a neutral atom, electrons = protons = 8.

Step3: Calculate neutron count

Oxygen's atomic mass is ~16. Neutrons = Atomic Mass - Atomic Number = $16 - 8 = 8$.

Step4: Fill electron shells

Bohr model rules: 1st shell holds max 2 electrons, 2nd shell holds max 8. For oxygen: 1st shell = 2 electrons, remaining $8-2=6$ electrons in 2nd shell.

Answer:

Element Box:

• Atomic #: 8
• Element Symbol: O
• Element Name: Oxygen
• Atomic Mass: 16

Particle Counts:

• # of Protons (+): 8
• # of Electrons (-): 8
• # of Neutrons: 8

Bohr Model Details:

• Nucleus: 8 P⁺, 8 N
• 1st innermost electron shell: 2 electrons
• 2nd electron shell: 6 electrons

(The outermost third shell remains empty as oxygen only uses the first two shells for its electrons)
