Sodium (Na) has an atomic number of 11, which means it has 11 protons, regardless of its isotope. The notation "Na-3" suggests it is a hypothetical isotope of sodium with an Atomic Mass of 3, but this is not stable or commonly recognized. In any case, the number of protons in sodium remains 11.

Yes!
Ba(Na3)
It would have 8 protons, 9 neutrons and 8 electrons.
The element that has half as many protons as zinc would be copper. Zinc has 30 protons, while copper has 29 protons. This means that copper has one less proton than zinc, making it the element with half as many protons.
There is no Na3. The atomic weight for sodium (Na) on the periodic table is 22.989770.
Carbon has 6 protons.
Yes!
Ba(Na3)
Oh, dude, Na3? That's sodium, right? So, like, each sodium atom has a charge of +1 because it loses an electron to become stable. So, if you have three sodium atoms together in Na3, you just add up their charges, which gives you a total charge of +3. Easy peasy.
NA3 is not a valid chemical notation. It is possible that it is a typo or a misunderstanding. Could you provide more context or clarify the question so I can help you better?
Na3'za Or Naghza ;)

Sodium phosphate-Wikipedia.
If an atom has a balanced charge, it means that the number of protons equals the number of electrons. So, you would expect to find the same number of protons as the atomic number of the element.
Look at it's atomic number. That shows the number of protons it contains
The element chromium has 24 protons in its nucleus. Therefore, an isotope of chromium with 54 as its mass number would still have 24 protons.
