Binary Compounds and Naming Systems

The video tutorial covers the naming of binary ionic compounds with multiple charges. It begins with an introduction to binary compounds, explaining the difference between molecular and ionic types. The tutorial then delves into ionic compounds, discussing set and multiple charges, and how to determine these charges using electronegativity. An example using copper chloride illustrates the process of charge determination and balancing. Finally, the video explains the Stock system for naming compounds, using Roman numerals to represent different charges, as standardized by the IUPAC.

What are the three groups of binary compounds discussed in the video?

• Molecular, binary ionic with set charges, binary ionic with multiple charges

• Molecular, ionic, covalent

• Binary, ternary, quaternary

• Ionic, covalent, metallic

What does the term 'binary' refer to in chemistry?

• Compounds with two elements

• Compounds with four elements

• Compounds with three elements

• Compounds with one element

What is the main difference between molecular and ionic compounds?

• Molecular compounds are metals, ionic are non-metals

• Molecular compounds are non-metals, ionic are metals

• Molecular compounds are solids, ionic are gases

• Molecular compounds are gases, ionic are liquids

Which part of the periodic table contains elements with set charges?

• First two rows

• Transition metals

• Halogens

• Noble gases

What is the range of charges that transition metals can have?

• From -1 to +1

• From +1 to +7

• From 0 to +3

• From -2 to +2

In the example of copper chloride, what is the charge of chlorine?

• Positive one

• Positive two

• Negative two

• Negative one

How do you determine the charge of copper in copper chloride?

• By looking at the color

• By guessing

• Using algebra and problem-solving

• By measuring the weight

What system is used to name compounds with multiple charges?

• The Ionic system

• The Stock system

• The Binary system

• The Roman system

What does the Stock system use to represent the charge of a metal?

• Arabic numerals

• Greek letters

• Chemical symbols

• Roman numerals

Where can you find the Roman numerals for the Stock system?

• On a separate chart

• On the periodic table

• In the bottom left corner of the sheet
