Question

What is the atomic number of the daughter element produced if an alpha particle is emitted from 238/92 U ​

Answer 1

Answer:

So here, the new mass number of the atom will be 238−4=234 , and the new element will have atomic number of 92−2=90 , which is thorium

Answer 2

Answer:

HEY MATE HERE IS YOUR ANSWER

ANS )

The equation for Alpha decay :-

A A-4 4

X ---> X + Alpha

Z Z-2 2

Where,

Z = Atomic number

A = Mass number

X = Symbol of the element

238 - 4 = 234 92 - 2 = 90

Thorium (Th)

234

Th

90

238 234 4

U ---> Th + Alpha

92 90 2

Final ans,

234

Th

90
