Energy Levels & Electron Configuration

The video tutorial explains the structure of an atom, focusing on protons, neutrons, and electrons. It details how electrons are arranged in shells around the nucleus, with specific examples of lithium, carbon, and magnesium. The tutorial also covers how electron configurations determine an element's reactivity and its group on the periodic table.

What does the electronic configuration of carbon look like?

Explain how the number of electrons in the outer shell affects an element's reactivity.
