1. decide where (what kind and how many) of your elements subatomic particles fit in an atom. tell me in complete sentences.

a. in the nucleus
b. energy level (shell) 1(max of 2)
c. energy level (shell) 2 (max of 8)
d. energy level (shell) 3 (max of 18)

1. use the blank model on the last page to create a bohr model of your atom. check off the items as you add them to your model.

include:
a color key for the different particles.
atoms name & symbol

Explanation:

Step1: Recall atomic structure facts

Protons and neutrons are in the nucleus. For oxygen, atomic number is 8, so number of protons is 8 and mass - number (approx. 16 for common oxygen) gives number of neutrons as 16 - 8=8.

Step2: Determine electron distribution

Electrons are in energy - levels. First energy - level can hold max 2 electrons, second can hold max 8. Oxygen has 8 electrons. So, 2 in first level and 6 in second level.

Step3: Answer part 3 questions

a. In the Nucleus, there are 8 protons and 8 neutrons.
b. Energy Level (Shell) 1 (max of 2) has 2 electrons.
c. Energy Level (Shell) 2 (max of 8) has 6 electrons.
d. Energy Level (Shell) 3 (max of 18) has 0 electrons.

Answer:

a. There are 8 protons and 8 neutrons in the nucleus.
b. There are 2 electrons in Energy Level (Shell) 1.
c. There are 6 electrons in Energy Level (Shell) 2.
d. There are 0 electrons in Energy Level (Shell) 3.
