Chemical Formulas

Universal laws and other relationships are used to analyze, understand, and explain chemical interactions and phenomena in everyday life.

What chemical laws or relationships can be applied to or derived from a given system?

A system is a collection of interactive, interrelated, or interdependent structures.

How are the components and parameters of a system defined?
How can one system be considered a component of another system?

Patterns of constancy in systems can be observed, measured, and / or modeled.

What information do patterns provide about a system(s)?

Scientific processes are used to explore and understand a system.

What makes a process scientific?
In what ways can a system be scientifically examined?
Which scientific processes are most appropriate when studying a system and why?
What significant conclusions can be drawn from investigating a system?

ASSIGNMENT:

1. List 3 ionic compounds and 3 covalent compounds.

2. Write an explanation of how to tell the two apart. It will be important to use that information from our last unit in this unit! Let's make sure we have that down before moving on.

ASSIGNMENT:

1. As you watch the video above, create a double-bubble map comparing and contrasting empirical formulas with molecular formulas.

2. Share with a neighbor and record anything you may have missed.

3. Then, you will get a copy of the empirical and molecular formulas practice from me to complete.

ASSIGNMENT:

1. Take out a sheet of paper and divide it in fourths.

2. At the top of each section, write: "Naming Ionic compounds", "Naming Covalent compounds" and "Naming Acids" and "Naming atoms with Polyatomic ions".

3 .Watch the video on writing ionic formulas.

4. Write down the rules for naming ionic compounds in the corresponding section on your notes.

5. Play with the interactive link to the right of the video.

6. Then, get a copy of the ionic compounds practice from me to complete. You will finish the other sections of the notes later.

ASSIGNMENT:

1. Take out your notes on naming compounds.

2. Watch the video on naming covalent compounds and fill in that section of your notes.

3. Next, use the website to the right of the video for some practice.

4.Then, see me for a copy of the covalent compounds practice.

ASSIGNMENT:

1. Watch the video on polyatomic ions.

2. Then, watch the video on naming compounds with polyatomic ions and fill in that section of your notes. See me for a copy of the list of polyatomic ions to use, you will probably want it when practicing your acid naming next.

3. The last video is a video with a fun way to remember names of polyatomic ions. You may see me for a copy of common polyatomic ions.

ASSIGNMENT:

1. Watch the video on naming acids.

2. Fill in the final section of your notes on naming compounds.

3. Then, see me for naming acids practice.

ASSIGNMENT:

1) Review and practice naming compounds with some mixed-practice.

ASSIGNMENT:

Given several elements

a) Write the names and chemical formulas of ways that the elements below might combine to make 5 compounds.

b) Be sure to utilize oxidation numbers!

c) Identify the compounds as ionic or covalent and explain how the atoms come together to form the compound (Are electrons shared? Transferred? How many? Explain! You may use a dot structure to help explain how the atoms are coming together, but remember dot structures are different for ionic v covalent bonds!)

Pick from the following list of elements:
