An isobar of sodium is an atom that has the same mass number as sodium, which is 23. This means that the isobar of sodium will have the same total number of protons and neutrons as sodium.
However, since the atomic number of sodium is 11 (meaning it has 11 protons), its isobar will have a different number of neutrons.
Here are some examples of isobars of sodium:
- Magnesium-23: This isotope of magnesium has 12 protons and 11 neutrons, giving it a mass number of 23.
- Aluminum-23: This isotope of aluminum has 13 protons and 10 neutrons, giving it a mass number of 23.
It's important to note that while isobars have the same mass number, they are different elements with different chemical properties due to their varying number of protons.
