Polonium is a metal element. Atomic Mass of it is 209.
The number 218 in polonium-218 represents the total number of nucleons (protons and neutrons) in the nucleus of that specific isotope of polonium. It refers to the sum of protons and neutrons in the atomic nucleus of the polonium-218 atom.
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)
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Polonium's atomic mass is 209 grams.
84 protons, 84 electrons and 136 neutrons.
(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.
Polonium-210 has 126 neutrons.
In a nuclear reaction involving a polonium nucleus, the total charge and total mass number of the products must equal the charge and mass number of the polonium nucleus due to the conservation laws. The charge of the products will match the original charge, and the mass number of the products will be equal to the mass number of the polonium nucleus before the reaction. This ensures that both charge and mass are conserved in the process.
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.
The number 218 in polonium-218 represents the total number of nucleons (protons and neutrons) in the nucleus of that specific isotope of polonium. It refers to the sum of protons and neutrons in the atomic nucleus of the polonium-218 atom.
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
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)
The symbol Po-210 represents the radioactive isotope of polonium with an atomic number of 84 and a mass number of 210. Polonium-210 is a highly toxic substance that emits alpha particles during radioactive decay.
The more stable polonium atoms have 125 neutrons. As with other elements, polonium atoms can have varying numbers of isotopes (variants with different number of neutrons).Polonium has 33 isotopes ranging from 104 to 136 neutrons.
Polonium is a metal element. Atomic mass of it is 209.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Polonium's atomic mass is 209 grams.
Polonium had no influence on Einstein determining that mass and energy were interchangeable.
