First, look closely: Zooming in on the bottom-right Bohr model, I can count the electrons. The innermost shell has 2 electrons, the second shell has 8 electrons, the third shell has 8 electrons, and the outermost shell has 2 electrons. This gives a total of 20 electrons.
-
Next, find information: I need to identify the element with atomic number 20. I will now search for the element that has 20 protons.
-
Then, review the findings: The element with atomic number 20 is Calcium (Ca). I have successfully identified all six elements.

Final Answer:
- Top-left: Carbon
- Top-right: Sodium
- Middle-left: Silicon
- Middle-right: Beryllium
- Bottom-left: Lithium
- Bottom-right: Calcium
