Calling All High School Parents Seeking Extra Support for

AP Chemistry!

AP Chemistry Unit Companion

Atomic Structures and Properties

Are you looking for a way to help your teen truly understand AP Chemistry Unit 1: Atomic Structure and Properties?

Look no further! Introducing the AP Chemistry Unit Companion!

A comprehensive video guide designed to accompany your child’s studies, just like having a personal tutor by their side.

Imagine having a trusted guide to walk them through Unit 1, ensuring they’re prepared for what comes next in the course.

Here's how.

As a parent, you might notice your teen struggling to grasp certain topics in class or feeling lost in their self-study efforts.

AP Chemistry is a challenging course, and understanding foundational concepts is key to success.

Whether your child is homeschooling or attending a traditional high school, this Unit Companion provides the extra support they need.

Designed by an experienced science teacher and tutor, this comprehensive video guide is built to help your student overcome the most common challenges in learning AP Chemistry,

such as...

Struggling with Complex Concepts

Topics like atomic structure and periodic trends in terms of Coulomb's law can be tough to grasp.

Finding Reliable Resources

Searching for practice problems and clear explanations can be overwhelming.

Need for Additional Practice

The classroom isn’t always enough to master every topic, especially as students prepare for the AP exam.

Think of this guide as an additional teacher—a personal tutor providing expert instruction at a fraction of the cost.

With my years of experience teaching and tutoring AP Chemistry, I’ve carefully structured these lessons to ensure your teen gets the support they need.

See an example of a step-by-step answer key with Topic 1.4 Composition of Mixtures!

Topic Covered:

1.1 Moles and Molar Mass

This topic introduces the mole as a fundamental concept in chemistry. Students will learn to calculate molar mass and convert between mass, moles, and number of particles in chemical equations.

1.2 Mass Spectra of Elements

Students explore how mass spectrometry provides insight into the isotopic composition of elements. They will learn to interpret mass spectra to determine the relative abundance and masses of different isotopes.

1.3 Elemental Composition of Pure Substances

This topic covers the quantitative relationship between the elements that make up a pure substance. Students will calculate the elemental composition by mass and use empirical and molecular formulas to describe the composition of substances.

1.4 Composition of Mixtures

Students will differentiate between pure substances and mixtures, and learn to determine the relative proportions of components in a mixture. This topic emphasizes understanding how chemical composition is analyzed and quantified in mixed systems.

1.5 Atomic Structure and Electron Configuration

This section covers the arrangement of electrons in atoms and ions based on quantum mechanical models. Students will learn to write electron configurations and understand how atomic structure relates to chemical properties.

1.6 Photoelectron Spectroscopy

Students are introduced to photoelectron spectroscopy as a method for determining the energies of electrons in atoms. They will analyze PES data to understand electron subshell energy levels and how this data relates to atomic structure.

1.7 Periodic Trends

This topic explains the periodic trends observed across elements in the periodic table, such as atomic radius, ionization energy, and electronegativity. Students will learn how these trends relate to electron configuration and atomic structure.

1.8 Valence Electrons

Valence electrons play a key role in chemical bonding and reactivity. Students will explore the concept of valence electrons and learn how to identify them for different elements based on electron configurations and the periodic table.

Who is This For?

This Unit Companion is perfect for students who:

Have taken high school chemistry and Algebra I and want to deepen their understanding.
Are looking for self-study resources for AP Chemistry to prepare for the exam.
Want additional practice on specific topics to reinforce what they’re learning in the classroom.
Need a structured and thorough way to review Unit 1 and build a strong foundation for future units.

Hi There! I'm Kesha (but my students call me Doc!)

I’m a scientist nerd who left the lab to follow a passion for teaching in 2002 and has been teaching ever since.

I'll be honest: chemistry and physics didn't come easily to me in high school and my first year in college.

Don’t get me wrong, I loved science. And my poor Barbie Dolls that became victim to my chemistry set are proof! But it wasn’t easy when sitting in class!

By the second year in college, I finally began to truly understand the subjects and learn what teaching methods work and what don't. And I LOVE them!!

Today, I support my students in learning and staying motivated in a subject area that intimidates most. I make it make sense with a dash of fun!
