Explore the atom as the basic building block of matter, detailing its nucleus with protons and neutrons, outer electrons, and the concept of electron clouds and shells.
Lesson 1: Practice Problems & Solutions. Practice what you just learned!
Learn how atoms form elements and how the periodic table groups 118 elements by protons, symbols, and masses. Explore symbols, atomic numbers, and the concept of isotopes and ions.
Explore how valence electrons determine bonding and ion formation, learn the octet rule and exceptions, and distinguish isotopes by neutrons in the periodic table.
Lesson 2: Practice Problems & Solutions. Practice what you just learned!
Learn how metals transfer electrons to nonmetals to form ions and ionic compounds like table salt, where opposite charges attract to form crystal lattices, unlike covalent bonds.
Learn how covalent bonding forms when atoms share electrons to fill valence shells, with examples like water, carbon dioxide, oxygen, acetaminophen, caffeine, and lactose and various bond types.
Lesson 3 Practice Problems & Solutions. Practice what you just learned!
Determine the center atom and count total valence electrons to build Lewis structures for molecules. Place bonds and fill octets, applying electronegativity and adding double or triple bonds when needed.
Lesson 4 Practice Problems & Solutions. Practice what you just learned!
Learn to name ionic compounds by balancing charges between the cation and anion, applying the -ide ending, and using roman numerals for transition metals, with practical examples.
Learn the rules for naming simple covalent molecules, using prefixes such as di, tri, and the correct order of elements; recognize examples like carbon dioxide and sulfur hexafluoride.
Lesson 5 Practice Problems & Solutions. Practice what you just learned!
Trace the evolution from Dalton to the electron cloud and quantum mechanics; learn how four quantum numbers (N, L, M_L, M_S) locate an electron and apply the Pauli exclusion principle.
Explore how quantum numbers define atomic orbitals, from energy shells (n) to orbital shape (l) and orientation (m_l), with spin (m_s) shaping electron occupancy.
Lesson 6 Practice Problems & Solutions. Practice what you just learned!
Explore covalent bonding through orbital overlaps, Lewis structures, and hybridization concepts, including sp, sp2, and sp3, with water, carbon dioxide, and HCN examples.
Master electron configurations and diagrams by filling orbitals in the correct order with periodic table guidance, and apply quantum numbers and Aufbau, Pauli, and Hund's rules.
Lesson 7 Practice Problems & Solutions. Practice what you just learned!
Convert Lewis structures to three-dimensional shapes using vsepr; count electron pairs around the central atom to determine geometry (linear, bent, tetrahedral, trigonal planar, trigonal bipyramidal, octahedral) with examples.
Lesson 8 Practice Problems & Solutions. Practice what you just learned!
First and foremost, this course assumes you have no prior knowledge of chemistry. It is designed to build a strong foundation in the concepts of chemistry. Ideally for students needing to take a chemistry course in high school, college students needing a refresher before taking college chemistry, or adults who just want to refresh what they learned about chemistry but have forgotten.
This course was designed around the General Chemistry curriculum that I spent three years teaching at a top US university. My teaching style and ability to relate technical content to students without “vomiting science” at students caused me to be sought by students who were struggling in chemistry for extra help and tutoring. I truly enjoy teaching chemistry and my passion for this subject shines throughout this course. Taking this course will help you stop worrying and love chemistry!
There are multiple introductory classes out there, why take this one?
Comprehensive Coverage: This curriculum covers all the essential topics of high school chemistry, providing a thorough foundation in the subject.
Engaging and Interactive Content: This course employs a variety of multimedia resources, including videos, simulations, and interactive exercises, to make learning chemistry exciting and accessible.
No Algebra Pre-Requisite! This course is primarily focused on the concepts rather than the "hard math". Algebra 1 is not required for this course, only the ability to add, subtract, multiply, and divide. Dr. G explains all other math necessary as part of the course.
Structured Learning Path: The curriculum is organized in a logical and sequential manner, ensuring a smooth progression of concepts and skills.
Experienced Instructor: I have taught at multiple levels from elementary school through college, he understands the benefit of making tough scientific concepts accessible to students.
Flexibility and Accessibility: Being an self-paced curriculum, it offers the flexibility to learn at one's own pace, anytime and anywhere, making it an ideal choice for homeschooling or prepping for college chemistry.
