Lewis Structures and Ionic Charges

This video tutorial explains how to write the Lewis structure for ammonium phosphate (NH4)3PO4. It covers the individual structures of the ammonium ion (NH4+) and the phosphate ion (PO4 3-), detailing their charges and how they combine to form a neutral compound. The video also provides links to additional resources for learning about individual Lewis structures.

What is the main focus of the video tutorial?

• Learning about ionic bonds

• Understanding molecular geometry

• Balancing chemical equations

• Writing the Lewis structure for ammonium phosphate

What charge does the ammonium ion (NH4+) carry?

• Positive one

• Neutral

• Negative one

• Negative three

Which ion is described as having a three minus charge?

• Nitrate ion

• Phosphate ion

• Ammonium ion

• Sulfate ion

How do the charges of NH4+ and PO4 3- contribute to the compound's neutrality?

• They both have negative charges

• They do not affect the compound's charge

• They both have positive charges

• Their charges balance each other out

What is the first step in drawing the Lewis structure for NH4+?

• Drawing the electron pairs

• Balancing the charges

• Placing NH4+ ions around the phosphate

• Drawing the phosphate ion

Where should the charge of the ammonium ion be indicated in the Lewis structure?

• It is not indicated

• Inside the brackets

• Next to the phosphate ion

• Outside the brackets

What is the purpose of resizing the NH4+ ions in the structure?

• To balance the charges

• To make room for the phosphate ion

• To fit them into the video frame

• To make them more visible
