Chemicals/Nitrogens/Quiz

Nitrogens is an effort, in a lecture format, to describe the chemicals that are the element nitrogen.

The red light depicts nitrogen emission ([N II] 658.4 nm); green, hydrogen (H-alpha, 6563A); and blue, oxygen (5007A). These are "cometary knots" in the Helix nebula. Credit: NASA Robert O Dell Kerry P. Handron Rice University, Houston Texas.

You are free to take this quiz based on the lecture nitrogens at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{chemistry resources}} and {{geology resources}} templates. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!
