Question

Question 4 5 pts The objective of this molecular drawing and visualization exercise is to determine the normal number of chemical bonds nitrogen can form (normal valence of nitrogen). Instructions: 1. Delete the water molecule by right clicking the central atom. 2. Click on the "Draw Tool" (tab 1 in the above picture); clicking on the drop down menu to select "Nitrogen(8)"; make sure that "Adjust Hydrogens" is checked; click on the OpenGL window to display the ammonia molecule. If you make a mistake,right click on the atom will delete it. To rotate the view, click the "star" tab (tab 2 in the above picture), and then click the molecule and drag to rotate What is the valence of nitrogen?

Explanation / Answer

nitrogen has 5 valence electron

5 answer

Nitrogen has five valence electrons; that is, five electrons in its outermost shell. These electrons may bond covalently with the electrons in other atoms in order to fulfill the "octet rule", which would give nitrogen the 8 valence electrons it wants.

We say that nitrogen has a valency of 3, meaning that it wants three more electrons in its outer shell. NH3, for instance, is an example of nitrogen bonding covalently with three hydrogens (which each have one valence electron) to give the nitrogen a full eight electron in its valence shell. However, an atom may make more than one bond with another atom. Keep this in mind.
