Question

Which letter is short hand notation
represents the principal energy
level?​

Answer 1

Explanation:

Electron configurations tell you the occupied electron orbitals for any given element. This is important in physics and chemistry because the properties of the outer shell in particular determine how the element will behave. For lead, however, the configuration gets very long, because lead has 82 electrons, and so it would be time-consuming to write out in full. However, the “shorthand” electron configuration offers a shortcut that saves a lot of time and makes the configuration easier to read.
