Answer:

The answer to your question is 234.

Step-by-step explanation:

Alpha emission is a type of radioactive composed on two positive charges and two neutrons, its total mass is 4, the element with these characteristics is Helium.

Then,

Uranium-238 ⇒ Thorium-234 + Helium-4

Because 234 + 4 = 238
