Atomic Structure Mastery | GCSE Chemistry Essentials

Welcome to The Chemistry Tutor! In this video, we’re unraveling the complexities of atomic structure, a fundamental topic in GCSE Chemistry. This comprehensive guide is designed to help you understand the key concepts of atomic theory and how atoms are structured.
What You’ll Learn in This Video:
Nuclear Model & Subatomic Particles: Explore the nuclear model of the atom and the roles of protons, neutrons, and electrons.
Relative Electrical Charges: Understand the relative electrical charges of subatomic particles and how they influence atomic behavior.
Electrostatic Attraction: Discover the concept of electrostatic attraction and how it holds the atom together.
Atomic Number: Learn about the atomic number and its significance in determining an element’s identity.
The Size of Atoms: Get insights into the size of atoms and the factors affecting their dimensions.
Relative Mass of Subatomic Particles: Compare the relative masses of protons, neutrons, and electrons to understand their contribution to atomic mass.
Mass Number & Atomic Number: Explore the relationship between mass number and atomic number, and how they are used to identify different isotopes.
Protons, Neutrons, and Electrons: Learn how to determine the number of protons, neutrons, and electrons in an atom and its implications.
Ions: Understand the formation of ions and their role in chemical reactions.
Electronic Structure: Dive into the electronic structure of atoms, including electron arrangements and energy levels.
Electron Arrangements for Key Elements: Examine the electron arrangements for Lithium, Aluminium, Chlorine, and Potassium, and see how these arrangements influence their chemical properties.
Our clear explanations and visual aids will help you master atomic structure and its foundational concepts.
