As you know, in his solar system model Bohr proposed that electrons are located in energy levels. The current model of the atom isn’t as simple as that, however. Sublevels are located inside energy levels just like subdivisions are located inside cities. Each sublevel is given a name.
An electron configuration is a method of indicating the arrangement of electrons about a nucleus. A typical electron configuration consists of numbers, letters, and superscripts with the following format: A number indicates the energy level (The number is called the principal quantum number.).
Electrons are distributed in the electron cloud into principal energy levels (1 , 2,3 ) sublevels (s, p, d, f), orbitals (s has I , p has 3, d has 5, f has 7) and spin (two electrons allowed per orbital),
The different values of n correspond to the allowed energies that the electron can have. These energies are called “energy levels”. The lowest energy level has n = 1 and is called the ‘ground state’. All other energy levels are called ‘excited states’. The average size of the electron’s orbit is also controlled by the value of n: r
8. The following diagram shows 5 different energy levels (n) that electrons can occupy. Use the diagram to answer each of the following questions: a. EXAMPLE Give a situation that could result in an electron making a quantum leap. An electron gains energy and moves from n=1 to n= 3. b. Give a situation that would result in an electron giving ...

Worksheet #1: Atomic Spectra 1. How did Bohr expand on Rutherford’s model of the atom? 2. Compare the energy of an electron in the ground state and an electron in the excited state. 3. When an electron falls from a higher energy level to a lower energy level, how is the energy released? 4.
