∙ 14y ago218 is the Atomic Mass of the Polonium isotope.
Polonium is a naturally radioactive metallic element, occurring in minute quantities as a product of radium disintegration and produced by bombarding bismuth or lead with neutrons. It has 27 isotopes ranging in mass number from 192 to 218, of which Po 210, with a half-life of 138.39 days, is the most readily available. Atomic number 84; melting point 254°C; boiling point 962°C; specific gravity 9.32; valence 2, 4.

What does the 218 in -218 polonium represent?
218Po (or polonium 218) is an isotope of polonium; 218 is the mass number of this isotope. The exact mass is: 218,0089730(26); the half life of this isotope is 3,10(1) minutes.
What are the dangers of polonium 218?
Polonium-218 is radioactive.
Which path would decay polonium 218 to bismuth 214?
Polonium-218 decay to lead-214.
What pathway would decay polonium-218 to bismuth-214?
Polonium-218-------------alpha---------------Lead-214
What happens to polonium when beta particles are emitted?
The beta minus decay of polonium isotopes is extremely rare. Beta decay involve the increase of the atomic number with 1.Example: Po-218----------------beta minus---------------At-218
What element does an atom of polonium change into after it emits an alpha particle?
Polonium 210-----------alpha particles-----------Lead 206 Polonium 209-----------alpha particles-----------Lead 205 Polonium 208-----------alpha particles-----------Lead 204 Polonium 214-----------alpha particles-----------Lead 210 Polonium 218-----------alpha particles-----------Lead 214 (99,98 %) Polonium 218-----------beta particles------------Astatin 218 (o,o2 %) For other isotopes see the list at: http://en.wikipedia.org/wiki/Polonium#Isotopes
How is the structure of the nucleus of a polonium 218 atom different from the structure of the nucleus of a radon 222 atom?
Polonium-218 has 84 protons, 84 electrons and 134 neutrons.Radon-222 has 86 protons, 86 electrons and 136 neutrons.
What is the number of protons in an atom of Polonium?
Polonium has 84 protons.
What is the number of neutrons in a polonium atom that has a mass number of 210?
Polonium-210 has 126 neutrons.
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)
What is the odd number of 218?
218 is an even number, not odd!
What number of moles of polonium represented by 3.18 and times 1024 atoms of polonium?
The number of moles is 0,528.
