Nitrogen is an element that exists in our atmosphere as a colorless, odorless, tasteless gas. Molecular nitrogen (14 N 2) is largely transparent to infrared and visible radiation because it is a homonuclear molecule and, therefore, has no dipole moment to couple the electromagnetic radiation at these wavelengths. The only time I ever hear it is when my students recite the visible spectrum. Spectral ranges are available by name including numerical value (eg grey56, s532) 1. Iron. It is a major component of chlorophyll, the most important pigment needed for photosynthesis, as well as amino acids, the key building blocks of proteins. The electrons fall from a higher energy state to a lower energy state or vice versa emitting or absorbing wavelengths of different magnitude which fall directly on the spectrum of hydrogen thereby releasing colours of various wavelengths and creating a continuous spectrum . Nitrogen, symbol N, has a Simple Hexagonal structure and Colorless color. Aluminum. If indigo counts as a color then so should canary, and mauve, and puce, and brick, and teal, and so on. shift in radiation frequency. Should not be too high or some line Scale: wavelengths in nm.
