Explanation:

Step1: Determine the number of protons

The number of protons is equal to the atomic number of the element.

• Carbon (C) has an atomic number of 6.
• Chromium (Cr) has an atomic number of 24.
• Nitrogen (N) has an atomic number of 7.
• Sulfur (S) has an atomic number of 16.

Step2: Calculate the number of neutrons

The number of neutrons is calculated by subtracting the atomic number from the mass number (isotope number).

• For Carbon - 12: \(12 - 6=6\)
• For Carbon - 13: \(13 - 6 = 7\)
• For Carbon - 14: \(14 - 6=8\)
• For Chromium - 58: \(58 - 24 = 34\)
• For Chromium - 63: \(63 - 24=39\)
• For Nitrogen - 15: \(15 - 7 = 8\)
• For Nitrogen - 20: \(20 - 7=13\)
• For Sulfur - 23: \(23 - 16 = 7\)
• For Sulfur - 25: \(25 - 16=9\)

Step3: Determine the number of electrons

In a neutral atom, the number of electrons is equal to the number of protons.

Answer:

	Carbon - 12	Carbon - 13	Carbon - 14	Chromium - 58	Chromium - 63	Nitrogen - 15	Nitrogen - 20	Sulfur - 23	Sulfur - 25
# of neutrons	6	7	8	34	39	8	13	7	9
# of electrons	6	6	6	24	24	7	7	16	16
