Your proton count, the atomic number, is 11. The mass is 23. This gives us the following: The element is determined by the proton count. Unless I’m very much mistaken, element 11 is sodium (or natrium, depending on where you live). We note isotopes as [element]- [atomic mass]. This means that your isotope is written as sodium-23. Homework question.What atom has 11 protons and 12 neutrons?
hydrogen, nitrogen, oxygen...?) If you have 11 protons and 12 neutrons this is an atom of what element? Any atom that contains exactly 11 protonsis an atom of sodium. The number of neutronsdoes not play a role in determining which element an atom is.What can the atomic mass tell you about an atom?
The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. It is traditionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an atom of neutral charge, atomic number is equal to the number of electrons.
