The correct option is C 1 and 2
1.
Radioactive decay is the process by which unstable atomic nuclei emit
subatomic particle or radiation.
2. When a radioactive nucleus decays, its nucleus
break up, emits an alpha particle or beta particle and energy, and forms a new atom
of a different element.
statement(s) given above are correct.
1.
Radioactive decay is the process by which unstable atomic nuclei emit subatomic
particle or radiation : Radioactive decay is the set of
various processes by which unstable atomic nuclei (nuclides) emit subatomic
particles (radiation). Decay is said to occur in the parent nucleus and
produces a daughter nucleus. This is a random process, i.e. it is impossible to
predict the decay of individual atoms.
2. When a radioactive nucleus decays, its nucleus
break up, emits an alpha particle or beta particle and energy, and forms a new atom
of a different element : Alpha decay. When an alpha particle
is emitted from the nucleus, the nucleus loses two protons and two neutrons.
This means the atomic mass number decreases by four and the atomic number decreases
by two. A new element is formed that is two places lower in the Periodic Table
than the original element.
