Polonium has 84 protons and electrons.
Polonium has 84 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - Atomic number of polonium (84)
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.
84 protons, 84 electrons and 136 neutrons.
209Po and 211Po are isotopes of polonium. 209Po and 211Po have the same number of protons and electrons, also the same atomic number; the number of protons is of course different. The two isotopes are radioactive.
the number of protons in an atom and the number of electrons in an atom
84 protons in polonium, as its atomic number is 84
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
Atomic number= 36 atomic number= no. of electrons
Polonium's atomic number is 84. That means it has 84 protons and 84 electrons. However, none of these electrons are found in the nucleus, but rather outside of it in what is called the electron cloud.
Electrons or atomic number. The atomic number is the number of protons as well as the principle quantum number.
