When the nuclide uranium-234 undergoes alpha decay: the name of the product nuclide is . the symbol for the product nuclide is?

a) Thorium

b)

Explanation:

Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.

General representation of an element is given as:  

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

General representation of alpha decay :

Hence the name of the product nuclide is Thorium and the symbol for the product nuclide is

h let me think
