^ means the number next to it is superscript
so the electron config. for lead is:
1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^10, 4p^6, 5s^2, 4d^10, 5p^6, 6s^2, 4f^14, 5d^10, 6p^2
then just re-group the numbers together, for example, if the numbers are set this way:
1s, 2s, 2p, 3s, 3p, 4s, 3d
make sure to put the 3d in the 4s place

How do you write out the electron configurations of solutions?
Solutions are mixtures of one or more solutes dissolved in a solvent. They do not have electron configurations. Only atoms and ions have electron configurations.
What are the examples of elements with predictable electron configurations?
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
