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.
What else can I help you with?
How many protons neutrons and electrons are in polonium?
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)
How many neutrons and protons in polonium 209?
84 protons, 84 electrons and 136 neutrons.
Which element has 84 protons 125 neutrons and 84 electrons?
(209) Po+4 The number of protons in an atom, ion, or molecule cannot change no matter what. Every Polonium atom and ion in the entire world has 84 protons. You find which element has 84 protons by looking at the 84th element on the periodic table. Now, every atom also has the same number of protons and electrons, but since this example is an ion, it must have more or less electrons than protons. Since there are 4 fewer electrons than protons, that means the ion is positive. So it would be Polonium with a +4 charge. the 209 is the atomic mass of the atom. There are several different isotopes of polonium. This one has 84 protons and 125 neutrons, thus you add them together to get the atomic mass of 209 amu.
What do you notice about the atomic number and the total number of electrons in an atom of that element?
The atomic number is equal to the number of protons in an atom, which also corresponds to the number of electrons in a neutral atom. This means that the atomic number gives you the total number of electrons in a neutral atom of that element.

How many protons are in polonlum?
84 protons in polonium, as its atomic number is 84
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
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
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
The atomic number of an element is what?
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.
If an f an atom has 36 electrons and 48 neutrons, then what is the atomic number?
Atomic number= 36 atomic number= no. of electrons
Explain how polonium -209 and polonium -211 are similar?
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... Is equal to the number of protons in an atom?
Electrons or atomic number. The atomic number is the number of protons as well as the principle quantum number.
