What happens to the position of an element in the periodic table when its nucleus emits a β particle. Give a reason for your answer.

Solution:

When a particle is emitted, the daughter element moves one position in the periodic table to the right of the parent element.
Reason: If a parent nucleus X creates a new daughter nucleus Y as a result of decay, the decay can be described as follows:


As the resultant nucleus has an atomic number equal to (Z+1), it moves one place to the right of the parent element in the periodic table.
