    The answer to your question is 234.

    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
