Question

instructions
choose one element of the first 10 in the periodic table (hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon). create a model of that atom showing the number of protons and electrons separated into electron orbits.

Explanation:

Let's choose oxygen. Oxygen has an atomic number of 8. So, it has 8 protons. In a neutral atom, the number of electrons is equal to the number of protons, so it has 8 electrons. The electron - configuration is 2 electrons in the first shell and 6 electrons in the second shell. To create a model, we can represent the nucleus with 8 protons (for simplicity, just write '8p' in the center). Then draw two concentric circles around the nucleus to represent the electron orbits. Put 2 electrons on the inner circle and 6 electrons on the outer circle.

Answer:

For oxygen: Nucleus with 8 protons. First electron - orbit has 2 electrons, second electron - orbit has 6 electrons.
