ELECTRON CONFIGURATION AND ORBITAL DIAGRAM.pptx

Electron Configuration

1. The energy sublevels of atoms are divided further into regions of space (orbitals). Each orbital can accommodate a maximum of 2 electrons. ENERGY SUBLEVELS energy sublevels Number of orbitals s 1 p 3 d 5 f 7

2. ELECTRON CONFIGURATION 05

3. Write the electron configuration of the following elements. SODIUM MAGNESIUM ALUMINUM SILICON PHOSPHORUS ELECTRON CONFIGURATION

4. Describes the manner in which energy sublevels are filled with electrons. The filling of energy sublevels in the order of increasing energy is called the Aufbau Principle (building up). ELECTRON CONFIGURATION

5. Are pictorial descriptions of the electrons in an atom. ORBITAL DIAGRAM
