Nitrogen is classified as an element in the 'Non-Metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metallic elements exist, at room temperature, in two of the three states of matter: gases (Oxygen, Hydrogen & Nitrogen) and solids (Carbon, Phosphorus, Sulfur and Selenium).
Transcript: Hi, this is Dr. B. Let's do the Lewis Structure for NI3, Nitrogen Triiodide. That's one of Dr. B.'s favorite chemicals: big explosion, nice purple cloud. So let's look on the periodic table.Nitrogen is in Group 5, sometimes called fifteen, so it has five valence electrons. And then for Iodine we have seven valence electrons but there's three of them so 5 + 21 = 26 total valence electrons. Let's put Nitrogen in the center.It is the least electronegative.o let's look on the periodic table. Nitrogen is in Group 5, sometimes called fifteen, so it has five valence electrons.
