Introduction to Elements Atoms and the Periodic Table

What is Introduction to Elements Atoms and the Periodic Table?

Introduction to Elements Atoms and the Periodic Table is a free online course offered by Alison US CA that provides a foundational understanding of chemistry. Designed for beginners, it explores the structure of atoms, the three subatomic particles—protons, neutrons, and electrons—and how they define chemical elements. The course explains valence electrons, orbitals, and electron configuration, helping learners grasp how elements are organized in the Periodic Table. You'll study ionization, the formation of ions, and the principles behind ionic, covalent, and metallic bonding. Coulomb's Law is introduced to explain the forces between charged particles.

Key features

• Atomic Structure — Learn about protons, neutrons, and electrons in detail.
• Periodic Table Trends — Understand periods, groups, and element classification.
• Chemical Bonding — Explore ionic, covalent, and metallic bonds.
• Ionization Process — Study how atoms gain or lose electrons to form ions.
• Valence Electrons — Focus on outer shell electrons and reactivity.
• Electron Configuration — Master orbital notation and energy levels.
• Free Access — No cost to enroll or complete the course.

Who is Introduction to Elements Atoms and the Periodic Table for?

This course suits high school students, college freshmen, or adult learners seeking a clear, structured introduction to chemistry. It’s ideal for those preparing for exams, refreshing core concepts, or exploring science topics independently. No prior chemistry knowledge is required, making it accessible to all skill levels.

How does Introduction to Elements Atoms and the Periodic Table compare?

Unlike paid chemistry courses or dense textbooks, this free Alison course delivers concise, modular lessons ideal for self-paced learning. It covers the same core topics as introductory college chemistry modules—atomic theory, bonding, and periodicity—but in a more digestible format. While it doesn’t include lab components like some academic courses, it excels in clarity and accessibility, especially for visual and digital learners.
