Q: What is the total number of neutrons in an atom of carbon-14? (2021)
Solution: Carbon-14 has an atomic number of 6 (6 protons). The mass number is 14, so the number of neutrons is 14 - 6 = 8.
Steps: 5
Step 1: Identify the atomic number of carbon. The atomic number of carbon is 6, which means it has 6 protons.
Step 2: Identify the mass number of carbon-14. The mass number is given as 14.
Step 3: Calculate the number of neutrons by subtracting the number of protons from the mass number. This is done by the formula: Number of neutrons = Mass number - Number of protons.
Step 4: Substitute the values into the formula: Number of neutrons = 14 - 6.
Step 5: Perform the subtraction: 14 - 6 = 8. Therefore, carbon-14 has 8 neutrons.
