Which element has highest ionisation potential?

Two elements A and B with atomic numbers Z_(A) and Z_(B) are used to produce characteristic X-rays with frequencies v_(A) and v_(B) respectively. If Z_(A):Z_(B) 1:2, then v_(A) :v_(B) will be

The concentration of each of Y^(-) and Z^(-) in a solution is 1 M. At 25^(@)C , a gas X at a pressure of 1 atm is allowed to pass through the solution. If the values of standard reduction potentials of X, Y and Z follows the order Z gt X gt Y , then which one between Y^(-) and Z^(-) would be oxidised by X?
