Nitrogen Lewis Structure Concepts

The video tutorial explains the process of drawing the Lewis structure for the N3- ion, also known as the Azide ion. It begins by identifying the number of valence electrons in nitrogen and the total for the ion. The tutorial then demonstrates arranging the nitrogen atoms and distributing electrons to form bonds. It explains how to move electrons to form double bonds, ensuring all atoms achieve octets. The video concludes with a complete Lewis structure where all atoms have full outer shells.

How many valence electrons does a single nitrogen atom have?

• 5

• 3

• 8

• 7

What is the total number of valence electrons in the N3- ion?

• 14

• 15

• 16

• 17

How are the nitrogen atoms initially arranged in the N3- Lewis structure?

• In a triangle

• In a circle

• In a line

• In a square

What is the purpose of moving a pair of electrons from the outer nitrogen atoms to the center?

• To achieve an octet for the central nitrogen

• To form a triple bond

• To decrease the number of valence electrons

• To increase the total number of electrons

How many valence electrons does the central nitrogen have after forming a double bond?

• 10

• 8

• 6

• 4

What is the final number of valence electrons used in the N3- Lewis structure?

• 17

• 14

• 16

• 15

What is the significance of achieving octets for all atoms in the N3- Lewis structure?

• It confirms the structure is complete

• It ensures the structure is unstable

• It increases the number of valence electrons

• It decreases the number of valence electrons
