Mastering Naming Ionic Compounds

The video tutorial introduces the concept of naming ionic compounds, starting with a fun safari theme. It covers the basics of naming cations and anions, including the use of Roman numerals for transition metals. The tutorial also explains how to identify and name polyatomic ions and demonstrates working backwards to determine charges. The session is interactive, with examples and exercises to reinforce learning.

What is the main topic of the lesson introduced in the video?

• Balancing chemical equations

• Naming ionic formulas

• Naming covalent compounds

• Understanding molecular geometry

In the example NaCl, what is the name of the cation?

• Chlorine

• Sodium

• Chloride

• Nitrate

How do you modify the name of an anion in an ionic compound?

• Drop the ending and add 'ide'

• Keep the original name

• Add 'ate' to the end

• Add 'ite' to the end

What is the name of the compound MgO?

• Magnesium oxide

• Magnesium oxite

• Magnesium oxine

• Magnesium oxalate

What is a polyatomic ion?

• An ion with only one element

• An ion with a positive charge

• An ion with multiple elements

• A single atom ion

Which of the following is a polyatomic ion?

• MgO

• K

• NaCl

• OH

How do you name a compound with a transition metal?

• Use the metal's name followed by 'ide'

• Use the metal's name followed by its charge in Arabic numerals

• Use the metal's name followed by its charge in Roman numerals

• Use the metal's name without any modification

What is the charge of copper in CuO?

• +1

• +2

• +3

• +4

How do you determine the charge of an anion?

• By its color

• By its mass number

• By its atomic number

• By its position in the periodic table
