Question

Radium with atomic no 88 and mass no 226 emits two alpha particles in two consecutive steps. It will produce element X after the first emission and element Y after the second emission. Write down the atomic no and mass no of the elements X and Y?

Answer 1

Answer:

Radioactivity is one of the most sinister phenomena studied by chemists and physicists. It occurs in the atomic level; in fact, in the nucleus of an atom.

Essentially, radioactive decay happens when an unstable atom wants to lose energy and become stable again. It does that by emitting something out of its nucleus, which transforms into a different nucleus or into a nucleus in a different state.

There are many different types of radioactive decay. One of the most common types is alpha decay: the nucleus emits an alpha particle, which is simply a helium nucleus with no electrons, and transforms into a nucleus with atomic number reduced by two units and mass number reduced by four units.
