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: neutrons: electrons: 8 o oxygen 15.9994

Explanation:

Step1: Determine number of protons

Atomic number of oxygen is 8, so protons = 8.

Step2: Determine number of neutrons

Atomic mass of oxygen is approximately 16. Neutrons = Atomic mass - Protons. So neutrons = 16 - 8=8.

Step3: Determine number of electrons

In a neutral atom, number of electrons = number of protons. So electrons = 8.

Step4: Place electrons in orbits

First orbit can hold 2 electrons, second orbit can hold 8. For oxygen with 8 electrons, 2 in first - orbit and 6 in second - orbit.

Answer:

Protons: 8
Neutrons: 8
Electrons: 8
(For the drawing: Draw a nucleus in the center. Label it with 8 protons and 8 neutrons. Draw two electron - orbits around the nucleus. Place 2 electrons in the inner orbit and 6 electrons in the outer orbit.)
