Ineed to find a, z and the element abbreviation for this nuclear equation problem. x is unknown. elements written in the following format. a, z abbreviation. here’s the problem: x + 0, -1 e- -> 233, 91 pa. find x.
i got more problems wrong, so if you can , that would be great.

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).
