Binding energy and orbital radius of the innermost electron vary with atomic ny

    How binding energy and orbital radius of the innermost electron vary with atomic no.

    Hi everyone,

    This is my first post on here, hope I'm doing everything as I should, let me know if I'm not!


    So here's the question I'm working on:

    For one thing, I don't know what the 'm' or the 'n' stand for. I think the rest are constants, except 'e' which is the charge on the electron. Am I correct in thinking that the 'h' is Planck's constant?

    I think these big messy equations are just frying my brain, and I can't see the answer at all.

    Any help will be much appreciated!
