Nitrogen and Its Ionic Forms

The video tutorial explains how to draw the Lewis structure for the nitride ion (N3-). It begins by illustrating the Lewis structure for neutral nitrogen, which has five valence electrons. The tutorial then adds three more electrons to account for the nitride ion's -3 charge, resulting in a full octet. The video concludes by emphasizing the importance of using brackets to denote the ion's charge.

What is the initial step in drawing the Lewis structure for the nitride ion?

• Identify the number of protons in nitrogen.

• Draw the Lewis structure for neutral nitrogen.

• Determine the molecular geometry of nitrogen.

• Calculate the atomic mass of nitrogen.

Which group does nitrogen belong to on the periodic table?

• Group 18

• Group 15

• Group 8

• Group 1

How many valence electrons does a neutral nitrogen atom have?

• 8

• 7

• 5

• 3

What is the charge of the nitride ion?

• -1

• 0

• -3

• -2

How many additional electrons are added to nitrogen to form the nitride ion?

• 2

• 4

• 1

What is achieved when nitrogen forms the nitride ion?

• A completely empty outer shell.

• A single electron in the outer shell.

• A half-filled shell.

• A full outer shell with an octet.

Why is it important to put brackets around the Lewis structure of the nitride ion?

• To show the ion's charge and complete notation.

• To highlight the atomic number.

• To indicate the presence of a covalent bond.

• To differentiate it from other ions.

What is the significance of achieving an octet in the Lewis structure?

• It suggests the atom is metallic.

• It indicates a stable electron configuration.

• It shows the atom is radioactive.

• It means the atom is a noble gas.
