Nitrate and Ammonium Ion Concepts

The video tutorial explains how to write the formula for ammonium nitrate by identifying the ammonium ion (NH4+) and the nitrate ion (NO3-). It describes the ionic nature of the compound, despite the absence of metals, due to the attraction between the positive ammonium ion and the negative nitrate ion. The tutorial also highlights the covalent bonds within the ions themselves.

What is the first step in writing the formula for ammonium nitrate?

• Locate ammonium on the periodic table

• Find the atomic number of nitrogen

• Identify the ammonium ion

• Determine the molecular weight

Which of the following best describes the ammonium ion?

• A metal ion with a neutral charge

• A single element with no charge

• A group of atoms with a positive charge

• A molecule with a negative charge

What is the chemical formula for the ammonium ion?

• NH2-

• NO3-

• NH4+

• NH3

What is the chemical formula for the nitrate ion?

• N2O

• NO3-

• NO2-

• NH4+

How do the charges of ammonium and nitrate ions affect the formula of ammonium nitrate?

• They form a covalent bond

• They create a net positive charge

• They create a net negative charge

• They cancel each other out to form a neutral compound

What type of bond is formed between the ammonium and nitrate ions?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

Why is ammonium nitrate considered ionic despite having no metals?

• Because it contains covalent bonds

• Due to its high melting point

• Due to the attraction between positive and negative ions

• Because it is a solid at room temperature

What type of bonds exist within the nitrate ion?

• Hydrogen bonds

• Metallic bonds

• Covalent bonds

• Ionic bonds
