Using Bohr’s rules, draw the lowest-energy configuration for the atom represented in Problem 4.56.

Data from Problem 4-56

It always takes energy to remove an electron from an atom, no matter what n shell the electron is in. Also, the higher the n, the more energy an electron starts out with.

Explain why it takes energy to remove an electron from an atom no matter what n shell it is in.

Why does it take less energy to remove an electron from an atom the higher its n value?
