Concept introduction:
The equations representing the changes that take place during radioactivity and other nuclear processes are called
The nuclear equation should be balanced just like the chemical equations.
In a balanced nuclear equation, the sum of the
The atom undergoing nuclear disintegration is called parent nuclide and the products obtained are called daughter nuclide.
The bombardment of neutron on nucleus increases the mass number by unit one.
The identity and symbol of the daughter nuclide formed by an alpha decay can be deduced from the
In an alpha decay, nucleus emits a particle with mass number 4 and atomic number 2 which is equivalent to helium nucleus. Thus, in an alpha decay, the mass number decreases by 4 and the atomic number decreases by 2. In a beta decay, nucleus emits an electron. During a beta decay, the mass number remains the same as electron has no protons or neutrons but atomic number increases by 1 as electron carries one unit of negative charge.
The symbols of neutron, alpha particle, and beta particle are
