What is group displacement law ? An element belonging to group 1 decay by `beta^(c-)-` emission. To which group of the periodic table the daughter element will belong ?

Explanation

Group displacement law `:` When a radioactive element emits
`a.` An `alpha-` particle, it is converted into an atom of a daughter element of atomic number two less and atomic mass four less than the parent element and the new element occupies a place two groups lower `(i.e., ` to the left `)` in the periodic table.
`b.` A `beta-` particle, it is converted into ta new element of the same atomic mass, but with atomic number one greater than the parent element and the new element occupies a place one group higher `(i.e.,` to the right `)` in the periodic table. The daughter table. The daughter element will belong to group `II` after `beta-`emmision.
