Explanation:

Step1: Recall atomic - structure rules

The atomic number is equal to the number of protons. In a neutral atom, the number of electrons is equal to the number of protons. The atomic mass is approximately the sum of protons and neutrons.

Step2: For the first atom (6 protons)

The atomic number is 6. The element with atomic number 6 is carbon (C). If we assume a common isotope, carbon - 12 has 6 neutrons (since atomic mass = protons+neutrons, and for carbon - 12, atomic mass = 12, 12=6 + neutrons). In a neutral atom, there are 6 electrons. It is a neutral atom (no ion), so charge = 0.
Protons: 6
Neutrons: 6
Electrons: 6
Atomic Mass: 12
Atomic Number: 6
Element Symbol: C
Element Name: Carbon
Ion: no
Charge: 0

Step3: For the second atom (7 protons)

The atomic number is 7. The element with atomic number 7 is nitrogen (N). A common isotope of nitrogen, nitrogen - 14, has 7 neutrons (14 = 7+neutrons). In a neutral atom, there are 7 electrons. It is a neutral atom (no ion), so charge = 0.
Protons: 7
Neutrons: 7
Electrons: 7
Atomic Mass: 14
Atomic Number: 7
Element Symbol: N
Element Name: Nitrogen
Ion: no
Charge: 0

Step4: For the third atom (8 protons)

The atomic number is 8. The element with atomic number 8 is oxygen (O). A common isotope of oxygen, oxygen - 16, has 8 neutrons (16 = 8+neutrons). In a neutral atom, there are 8 electrons. It is a neutral atom (no ion), so charge = 0.
Protons: 8
Neutrons: 8
Electrons: 8
Atomic Mass: 16
Atomic Number: 8
Element Symbol: O
Element Name: Oxygen
Ion: no
Charge: 0

Step5: For the fourth atom (9 protons)

The atomic number is 9. The element with atomic number 9 is fluorine (F). A common isotope of fluorine, fluorine - 19, has 10 neutrons (19 = 9+neutrons). In a neutral atom, there are 9 electrons. It is a neutral atom (no ion), so charge = 0.
Protons: 9
Neutrons: 10
Electrons: 9
Atomic Mass: 19
Atomic Number: 9
Element Symbol: F
Element Name: Fluorine
Ion: no
Charge: 0

Answer:

1. Protons: 6, Neutrons: 6, Electrons: 6, Atomic Mass: 12, Atomic Number: 6, Element Symbol: C, Element Name: Carbon, Ion: no, Charge: 0
2. Protons: 7, Neutrons: 7, Electrons: 7, Atomic Mass: 14, Atomic Number: 7, Element Symbol: N, Element Name: Nitrogen, Ion: no, Charge: 0
3. Protons: 8, Neutrons: 8, Electrons: 8, Atomic Mass: 16, Atomic Number: 8, Element Symbol: O, Element Name: Oxygen, Ion: no, Charge: 0
4. Protons: 9, Neutrons: 10, Electrons: 9, Atomic Mass: 19, Atomic Number: 9, Element Symbol: F, Element Name: Fluorine, Ion: no, Charge: 0
