    your log on custom scientific calculator is log to base 10. log( to the base 10 ) 10 would be 1.

    What does this have to do with ionisation energy?

    Always remember that Logx X = 1 (when the base and the number are same the value of log is 1)

    so log 10 to the base 10 is also 1.

    They sometimes display the ionisation energies on graphs using logs because the values get so high.

    oh i see, the trend would still be there for ionisation energies either down a group or across a period. all the best.
