The element symbol of polonium is Po. It is a radioactive element with atomic number 84.
The number 48 in the name krypton-84 represents the atomic number of the element krypton. Atomic number is the number of protons in the nucleus of an atom, determining its chemical properties.
An element's atomic number indicates the number of protons it has in the nucleus. In this case, since polonium's atomic number is 84, it has 84 protons. In a neutral atom, the number of protons is the same as electrons. This is because the positive charge of the protons in the nucleus must be balanced with by the negative charge of the electrons. Therefore, in this case, because polonium has 84 protons, it has 84 electrons.
