218 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?

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.


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 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 pathway would decay polonium-218 to bismuth-214?

Polonium-218 undergoes alpha decay to form lead-214, which then undergoes beta decay to form bismuth-214.


What element does an atom of polonium change into after it emits an alpha particle?

An atom of polonium changes into an atom of lead after it emits an alpha particle. This transformation occurs as a result of radioactive decay, where the polonium nucleus loses two protons and two neutrons, transforming it into a lead nucleus.


How is the structure of the nucleus of a polonium 218 atom different from the structure of the nucleus of a radon 222 atom?

The nucleus of a polonium-218 atom contains 84 protons and 134 neutrons, while the nucleus of a radon-222 atom contains 86 protons and 136 neutrons. This difference in the number of protons and neutrons results in different nuclear properties and stability for each atom.


When the nuclide astatine-218 undergoes alpha decay?

When astatine-218 undergoes alpha decay, it emits a helium nucleus (alpha particle) and transforms into the new element, polonium-214. This process reduces the atomic number of the nucleus by 2 and the mass number by 4.


What is the mass number of polonium?

Polonium is a metal element. Atomic mass of it is 209.


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.
