Answer:

233, 92 U

Explanation

I agree with your answer of 233 for the mass number (top number), but for the atomic number (bottom number) we need:

x + -1 = 91

Add 1 to both sides

x=92

Answer:

233, 92 U

Explanation:

A, Z X + 0, -1 e- -> 233, 91 Pa

To solve this you need to find the atomic mass and the atomic number of X. In order to balance the equation, the following must be satisfied:

A + 0 =  233

A =  233

Z - 1 = 91

Z = 92

The atomic number is 92, which correspond to Uranium (U).
