How many protons and neutrons are in oxygen?
Understand the Problem
The question is asking for the number of protons and neutrons present in an oxygen atom. Oxygen has a standard atomic number of 8, which means it has 8 protons. The most common isotope of oxygen has 8 neutrons, though other isotopes may have different neutron counts.
Answer
8 protons, 8 neutrons
The final answer is 8 protons and 8 neutrons.
Answer for screen readers
The final answer is 8 protons and 8 neutrons.
More Information
Most naturally occurring oxygen atoms have 8 protons and 8 neutrons, making up the 16O isotope. There are also other isotopes like 17O and 18O with different numbers of neutrons.
Tips
A common mistake is confusing the atomic number (protons) with the atomic mass (protons + neutrons). Always verify the specific isotope to determine the correct number of neutrons.
