Interpretation:
The blanks in the partial decay series are to be filled.
Concept Introduction: When an unstable nucleus emits a small part of itself that consists of 2 protons and 2 neutrons, it is known as an alpha decay
During an alpha decay, mass number decreases by 4 and
When an unstable nucleus emits an electron, it is known as beta decay
During beta decay, atomic number increases by 1.
When an unstable nucleus emits
When an unstable nucleus emits positron, the atomic number decreases by 1 and there are no changes in mass number.
