Atomic Structure and Electron Configuration

The video tutorial introduces nitrogen, element number seven on the periodic table, with an atomic mass of 14. It explains the atomic structure, including protons, neutrons, and electrons, and demonstrates how to configure electrons in shells. The tutorial concludes with encouragement to apply the learned pattern to other elements.

What is the atomic number of nitrogen?
