234 92U undergoes alpha decay. What is the atomic number of the resulting element. Express your answer numerically as an integer.

90

Explanation:

Let ʸₓA be the resulting element when ²³⁴₉₂U under goes alpha decay.

Thus, the equation is given below

²³⁴₉₂U —> ʸₓA + ⁴₂He

The atomic number x of the resulting element can be obtained as follow:

92 = x + 2

Collect like terms

92 – 2 = x

90 = x

Therefore,

x = 90

Thus, the atomic number of resulting element is 90.
