Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
Radon-222 decays by alpha decay to become polonium-218.
The sequence is:
222Rn------ 218Po------ 214Pb------ 214Bi----- 214Po------ 210Pb-------- 210Bi------- 210Po-------- 206Pb
The isotope 222Rn is an alpha particles emitter.
nucleus
The heaviest of all elements are formed by bombardment of two ions into each other ( eg Zinc and Lead) which then forms a highly unstable heavy element that very rapidly decays into smaller elements.
kinetic energy
The nucleus, it is like the brain of the cell.
in alpha decay it loses a helium nucleus (2 protons, 2 neutrons)in beta decay a neutron converts to a proton and it ejects an electron and a neutrinoin gamma decay an excited nuclear state relaxes and a gamma photon is emittedin "k-capture" an inner electron is eaten by the nucleus converting a proton to a neutron and it ejects a neutrinothere are also a few other mechanisms.
Though the electron itself is not present in the nucleus of an atom, the elementary particles that make up the electron are present inside the neutron. In other words, a neutron is made up of an electron and a proton. How do we know this? Because when a neutron decays, it slowly decays into a proton and an electron. It's a cycle.
Polonium-212 loses 2 protons and 2 neutrons when it decays to lead-208. These 2 protons and 2 neutrons are lost as a single Helium nucleus. In other words, it is an alpha decay.
nucleus
Nucleus of the standard isotope of carbon atom has 6 protons and 6 neutrons (carbon 12). Other Isotopes of carbon atoms are also possible, such as C14, which has 8 neutrons, and decays by beta particle emission into nitrogen.
This would be radioactivity in which alpha or beta particles are released. The nucleus concerned decays into another nucleus with lower energy, resulting in ejection of the particle which has kinetic energy, until it is absorbed into some other material which will happen quite quickly.

Hail is a product of cumulonimbus clouds. In other words, thunderstorms.

Hydrogen is the only fuel that forms exclusively water when burned. Other fuels will form water in addition to other by-products such as carbon dioxide.
Sometimes yes and other times no, it depends on the product really, but if you insist on chewing the product there must be a chew able form of it somewhere.
The heaviest of all elements are formed by bombardment of two ions into each other ( eg Zinc and Lead) which then forms a highly unstable heavy element that very rapidly decays into smaller elements.
The positively charged nucleus of each of the atoms attracts the shared electrons of the other atom and thus forms the covalent bond.
