Valence Electrons in N2H4

The video tutorial explains how to draw the Lewis structure for N2H4. It begins by calculating the total number of valence electrons, which is 14. The Nitrogens are placed in the center with Hydrogens on the outside. Two valence electrons are placed between atoms to form bonds, using all 14 electrons. The octet rule is checked, ensuring all Hydrogens and Nitrogens have full outer shells. The tutorial concludes with a confirmation that the N2H4 Lewis structure is complete.
