Question

part ii. for each of the following isotopes, write the number of protons, neutrons, and electrons. assume all atoms are neutral.

	carbon-12	carbon-13	carbon-14		chromium-58	chromium-63
# of protons				# of protons
# of neutrons				# of neutrons
# of electrons				# of electrons

Explanation:

Step1: Recall atomic number concept

The atomic number of carbon is 6 and of chromium is 24. In a neutral atom, number of protons = number of electrons.

Step2: Calculate for carbon - 12

Protons: 6 (atomic number of carbon). Neutrons: Mass number - Protons = 12 - 6 = 6. Electrons: 6 (since neutral).

Step3: Calculate for carbon - 13

Protons: 6. Neutrons: 13 - 6 = 7. Electrons: 6.

Step4: Calculate for carbon - 14

Protons: 6. Neutrons: 14 - 6 = 8. Electrons: 6.

Step5: Calculate for chromium - 58

Protons: 24. Neutrons: 58 - 24 = 34. Electrons: 24.

Step6: Calculate for chromium - 63

Protons: 24. Neutrons: 63 - 24 = 39. Electrons: 24.

Answer:

Isotope	# of protons	# of neutrons	# of electrons
Carbon - 13	6	7	6
Carbon - 14	6	8	6
Chromium - 58	24	34	24
Chromium - 63	24	39	24
