About This Chapter

The Atom in Physics chapter of this SAT Physics Tutoring Solution is a flexible and affordable path to learning about atomic structure. These simple and fun video lessons are each about five minutes long, and they teach all of the atomic theory and subatomic particles topics required in a typical SAT physics course.

How it works:

  • Begin your assignment or other SAT physics work.
  • Identify the atom concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our SAT Physics Tutoring Solution will benefit any student who is trying to learn about atoms to prepare for the subject test. This resource can help students, including those who:

  • Struggle with understanding early atomic theory, isotopes, average atomic mass, Avogadro's number, electron configurations, atomic spectra, quantum numbers or any other atoms topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their atoms unit
  • Cope with ADD or ADHD
  • Want to excel on the SAT physics subject test
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about atoms simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live physics tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about atoms on the go!
  • Learn at Your Pace: You can pause and re-watch lessons as often as you'd like, until you master the material.

Learning Objectives

  • Study early atomic theories from Dalton, Rutherford, Millikan and more.
  • Learn the structure of atoms and examine atomic number and mass number.
  • Review the significance of isotopes and calculations for average atomic mass.
  • Use Avogadro's Number to count atoms.
  • Study electron configurations in atomic energy levels and the four quantum numbers.
  • Review the Bohr Model and atomic spectra.

The Atom

1. The Atom

The physical basis that everything is composed of is called matter and the smallest unit of matter is called an atom. Learn about the atom, subatomic particles, the nucleus, elements, and the periodic table.

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

2. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

The current knowledge of atoms and atomic theory has been informed by many scientists going back to Aristotle and Democritus. Learn about the contributions made to early atomic theory by scientists working in more recent times, such as Dalton, Thomson, Rutherford, and Millikan.

Atomic Number and Mass Number

3. Atomic Number and Mass Number

An atom is defined as the smallest particle of an element that displays the same properties of that element. Learn about the main components of an atom (protons, neutrons, & electrons), the characteristics of each component, and how to determine the atomic number and the mass number of an atom.

Isotopes and Average Atomic Mass

4. Isotopes and Average Atomic Mass

Isotopes are variations of the same element with differing numbers of neutrons and, subsequently, different atomic masses. Learn how scientists consider isotopes when they calculate average atomic mass.

Electron Configurations in Atomic Energy Levels

5. Electron Configurations in Atomic Energy Levels

Electron configuration is the representation of how the electrons in an atom are arranged, which can be used to predict the properties of an element. Learn about patterns of energy levels in elements on the periodic table, how to identify the number of electrons in a neutral atom, and how to write an electron configuration for neutral atoms.

Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

6. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

Quantum numbers describe specific properties of an electron. Learn about atomic orbital, the four quantum numbers (principal, angular momentum, magnetic, and spin), and how to write quantum numbers based on electron configuration.

The Bohr Model and Atomic Spectra

7. The Bohr Model and Atomic Spectra

The Bohr model of the atom established the existence of a positive nucleus surrounded by electrons in specific energy levels. As electrons move from higher-energy to lower-energy levels, energy in the atom is released in the form of photons. Learn about the Bohr Model, atomic spectra, and how electrons emit different colors of light.

Matter: Physical and Chemical Properties

8. Matter: Physical and Chemical Properties

Matter, or material substances, are identified based on their physical and chemical properties. Explore how this process works and learn how chemists use different properties to determine the classification of matter.

States of Matter: Solids, Liquids, Gases & Plasma

9. States of Matter: Solids, Liquids, Gases & Plasma

There are four states of matter: solid, liquid, gas, and plasma. Explore the characteristics of each state of matter and how they relate to and differ from each other.

States of Matter and Chemical Versus Physical Changes to Matter

10. States of Matter and Chemical Versus Physical Changes to Matter

Matter constantly changes. Learn about the three states of matter, which are gas, liquid, and solid, and understand the differences in chemical versus physical changes in matter.

Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

11. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

Matter exists in four states: solid, liquid, gas, and plasma. There are six changes of phase that occur among these states. Learn more about the different kinds of phase change, their examples, and the energies involved in these changes.

Common Chemical Reactions and Energy Change

12. Common Chemical Reactions and Energy Change

The five common types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Explore these different reactions, how to predict reactions, and learn how energy changes.

Avogadro's Number: Using the Mole to Count Atoms

13. Avogadro's Number: Using the Mole to Count Atoms

Atoms are microscopic and challenging to count as a result. Learn about the importance of understanding the mole, which is simply a large number or quantity of something, also known as Avogadro's number, and how it helps scientists count large numbers of atoms.

Nuclear Reaction: Definition & Examples

14. Nuclear Reaction: Definition & Examples

A nuclear reaction, such as fission and fusion, affects the nucleus of an atom and changes its particles in the process. Explore the differences between nuclear reactions and chemical reactions, the differences between nuclear fission and fusion, and how they are used for energy.

Endothermic and Exothermic Reactions

15. Endothermic and Exothermic Reactions

In endothermic reactions, the system gains heat as the surroundings cool down, and in exothermic reactions, the system loses heat as the surroundings heat up. Explore the differences between these reactions and learn about chemical reactions and enthalpy.
