Question

bohr diagrams are another way to sketch atoms. here is a bohr diagram of the carbon atom: label the energy levels! there are rules to how many electrons can be in each energy level: - the 1st energy level can hold up to 2 electrons. - the 2nd energy level can hold up to 8 electrons. - the 3rd energy level can hold up to 8 electrons. here is an example on how to complete the practice below. sketch an atom label 6 protons in the nucleus. label 6 neutrons in the nucleus. draw 2 electrons in the 1st energy level. draw 4 electrons in the 2nd energy level. what element is represented? carbon sketch an atom label 8 protons in the nucleus. draw 8 neutrons in the nucleus. draw 2 electrons in the 1st energy level. draw 6 electrons in the 2nd energy level what element is represented? oxygen sketch an atom label 4 protons in the nucleus. draw 5 neutrons in the nucleus. draw 2 electrons in the 1st energy level. draw 2 electrons in the 2nd energy level what element is represented? sketch an atom label 15 protons in the nucleus. draw 16 neutrons in the nucleus. draw 2 electrons in the 1st energy level draw 8 electrons in the 2nd energy level draw 5 electrons in the 3rd energy level what element is represented? sketch an atom label 13 protons in the nucleus. draw 14 neutrons in the nucleus. draw 2 electrons in the 1st energy level. draw 8 electrons in the 2nd energy level draw 3 electrons in the 3rd energy level what element is represented?

Explanation:

To determine the elements for each "Sketch An Atom" section, we use the atomic number (number of protons) to identify the element, as the atomic number is unique to each element.

1. First "Sketch An Atom" (8 protons, 8 neutrons, 2 + 6 electrons)

• Protons = 8. The element with atomic number 8 is Oxygen (O).

2. Second "Sketch An Atom" (4 protons, 5 neutrons, 2 + 2 electrons)

• Protons = 4. The element with atomic number 4 is Beryllium (Be).

3. Third "Sketch An Atom" (15 protons, 16 neutrons, 2 + 8 + 5 electrons)

• Protons = 15. The element with atomic number 15 is Phosphorus (P).

4. Fourth "Sketch An Atom" (13 protons, 14 neutrons, 2 + 8 + 3 electrons)

• Protons = 13. The element with atomic number 13 is Aluminum (Al).

Final Answers (by section):

1. Oxygen
2. Beryllium
3. Phosphorus
4. Aluminum

(Note: For each section, the number of protons determines the element, as the atomic number (protons) defines the element. Electrons follow the energy - level rules (2 in 1st, 8 in 2nd, 8 in 3rd, etc.), which match the given electron counts here.)
