Question

bohr model drawing (25 points) draw a bohr - model of an oxygen atom in the space below. be sure to place the electrons in the correct orbitals and to fill out the key for the subatomic particles. key protons: 6 neutrons: 8 electrons: 6 8 o oxygen 15.9994

Explanation:

Step1: Recall oxygen's atomic number

Oxygen has an atomic number of 8, so it has 8 protons and 8 electrons in a neutral - state.

Step2: Determine number of neutrons

The atomic mass of oxygen is approximately 16. Subtracting the number of protons (8) gives 8 neutrons.

Step3: Place electrons in orbits

The first orbit can hold 2 electrons and the second orbit can hold 8. For oxygen with 8 electrons, 2 go in the first orbit and 6 go in the second orbit.

Answer:

In the Bohr - model drawing of an oxygen atom:

• Nucleus contains 8 protons and 8 neutrons.
• First electron - orbit (closest to the nucleus) has 2 electrons.
• Second electron - orbit has 6 electrons.
