Chirani Your chemistry tutor
I am Chirani Thammita Lennon who is an experience chemistry tutor for nearly a decade. I an experienced in guiding high school and college students with any needs through the guidance to make chemistry an enjoyable subject. I specialize in subjects like biochemistry, organic chemistry, atomic structure, and more in depth knowledge on the lab skills. Grasping complex concepts in chemistry is nothing to do with your knowledge but the way you approach it. Make chemistry a story, game or a fantasy novel. You just need to know the easy tricks all chemists use to gain their success. That’s where I come to play. I excel in covering all bases that is needed for you to excel in homework, lab assignments, group work and assignments that get You points and bonus points. Grades will be nice but understanding the concepts of chemistry is more important. Make sure you are comfortable with this “hard” subject!
Chirani graduated from PennWest University Edinboro

Chemistry class overview
My tutoring style structured, patient, interactive, and engaging, focusing on hands on learning experiences. I specialize in teaching chemistry in all sub groups such as states of , acid, bases and pH. It doesn’t matter if you want help in general chemistry or organic chemistry, i will help you succeed by making you understand the concept with the technique you prefer. Everyone studies and retain information different, spring feel afraid to reach out to tell me what you are compatible and comfortable with. My teaching techniques all include presentations, diagrams, note taking, color coding and many more. The most important method of teaching is communication. I like when You can contact me when you have any questions about any material we covered or any material you don’t understand but needs ur get help with. Therefore, let’s navigate chemistry together!

Chemistry concepts taught by Chirani
The tutor and student delved into VSEPR theory, intermolecular forces, and molecular geometry. They practiced identifying molecular shapes and understanding the principles behind different types of molecular attractions. The student was provided with a comprehensive chart and planned to review the material and work on practice problems for an upcoming exam.
Intermolecular vs. Intramolecular Forces
VSEPR Theory: Geometry and Shape
Molecular Polarity
Sigma (σ) and Pi (π) Bonds
The Tutor and Student reviewed key concepts in chemical bonding, including ionic and covalent bonds, Lewis structures, formal charge, and polarity. They practiced drawing molecular structures and calculating formal charges, with plans to further explore VSEPR theory and molecular geometry in the next session.
Types of Chemical Bonds
Ionic Bonding: Properties and Structure
Covalent Bonding: Polarity and Types
Lewis Structures and Formal Charge
Resonance and Stability
The student and tutor reviewed the fundamental concepts of chemical bonding, covering ionic, covalent, and metallic bonds. They practiced drawing Bohr and Lewis diagrams for atoms and molecules, and discussed the properties associated with each type of bonding. The next session will focus on drawing ionic and covalent bonds and writing chemical formulas.
Types of Chemical Bonds
Ionic Compounds: Structure and Properties
Covalent Compounds: Sharing is Caring
Intermolecular vs. Intramolecular Forces
The class reviewed key chemistry concepts including reading the periodic table, elements, atoms, and Bohr diagrams. The student practiced constructing Bohr diagrams for the first 20 elements and applying knowledge of atomic trends. The session also addressed the student's confusion regarding ionic bonding and Lewis structures, with plans to further practice these concepts and explore additional materials in upcoming sessions.
Atomic Trends: Radius and Reactivity
Bohr Diagrams
Reading the Periodic Table
Valence Shells and the Octet Rule
The Tutor and Student reviewed several chemistry topics including electron configurations, empirical and molecular formulas, percentage composition, types of chemical reactions, balancing chemical equations, and nomenclature. The Student practiced calculating empirical and molecular formulas, balancing equations, and identifying reaction types. They plan to cover bonding and Lewis structures in the next session.
Electron Configuration
Empirical and Molecular Formulas
Types of Chemical Reactions
Balancing Chemical Equations and Stoichiometry
Nomenclature of Inorganic Compounds
The tutor and student reviewed chemical reaction types and the classification of mixtures. The majority of the session was dedicated to the periodic table, covering atomic structure, element properties, and categories like metals, non-metals, and metalloids. The tutor provided a mnemonic for the first ten elements and discussed metallic character trends, with a plan to cover atoms and reactions in the next session.
