When radon-222 undergoes alpha decay, it transmutates into what daughter nucleus?

Answer : The daughter nucleus is, polonium (Po).

Explanation :

Alpha decay : In this process, alpha particles is emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units.

The general representation of alpha decay reaction is:

The complete alpha decay reaction will be,

From this we conclude that, when radon-222 undergoes alpha decay then it transmutates into polonium daughter nucleus.

Hence, the daughter nucleus is, polonium (Po).

the answer is false because not all countries have geysers under their crust. for example, iceland uses geothermal energy because it is available every in their country.  

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
