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 protons and neutrons in 209Po?

The atomic number of Bi is 83, so it has 83 protons and 126 neutrons.


What does the number -209 before polonium mean?

The number -209 indicates the atomic mass of the specific isotope of polonium known as Polonium-209. This isotope of polonium has 209 nucleons (protons and neutrons) in its nucleus, giving it an atomic mass of 209 atomic mass units.


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.


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.


How many proton neutrons and electrons does bismuth have?

bismuth has 83 protons and electrons.Bi-209 isotope has 126 neutrons.


What is the mass number of lead that has 127 neutrons?

The mass number of an atom is the sum of its protons and neutrons. Lead (Pb) has an atomic number of 82, so it has 82 protons. If it has 127 neutrons, the mass number would be 82 (protons) + 127 (neutrons) = 209.

How many protons neutrons and electrons in bismuth 210?

The chemical element, bismuth, has an atomic number of 83. That means that, assuming it's electrically neutral, it has 83 protons and 83 electrons. Since we know that this particular isotope of bismuth has a combined total of 205 protons and neutrons, the total number of subatomic particles in 205Bi; i.e., the total number of protons, neutrons, and electrons, is 205 + 83 = 288.
