Hi I am a trained senior teacher for chemistry and have experience in teaching IGCSE,Edexcel, IB, A level, Victorian curriculum and CBSE. I have written lecture notes explaining the concepts in chemistry chapter wise that gives a clear idea to new teachers and students about how to apply these concepts these concepts in solving exam questions. I have some excellent resources for new chemistry teachers and new form teachers of primary and secondary classes.

This resource I use to teach my IB and A Level Students about moles and stoichiometric relationships. Contents- States of Matter Laws of Chemical Combination Naming of Ionic and Covalent Compounds Valencies of common ions Mole Concept • The mole is a fixed number of particles and refers to the amount, n, of substance. • Masses of atoms are compared on a scale relative to 12C and are expressed as relative atomic mass (Ar) and relative formula/molecular mass (Mr). • Molar mass (M) has the units g mol-1. • The empirical formula and molecular formula of a compound give the simplest ratio and the actual number of atoms present in a molecule respectively. • Calculation of the molar masses of atoms, ions, molecules and formula units. • Solution of problems involving the relationships between the number of particles, the amount of substance in moles and the mass in grams. • Interconversion of the percentage composition by mass and the empirical formula. • Determination of the molecular formula of a compound from its empirical formula and molar mass. • Obtaining and using experimental data for deriving empirical formulas from reactions involving mass changes.

This is an excellent resource for teaching IB and A level Class about periodic table and periodic properties. Contents- • The periodic table is arranged into four blocks associated with the four sub-levels—s, p, d, and f. • The periodic table consists of groups (vertical columns) and periods (horizontal rows). • The period number (n) is the outer energy level that is occupied by electrons. • The number of the principal energy level and the number of the valence electrons in an atom can be deduced from its position on the periodic table. • The periodic table shows the positions of metals, non-metals and metalloids. • Deduction of the electron configuration of an atom from the element’s position on the periodic table, and vice versa. Transition elements have variable oxidation states, form complex ions with ligands, have coloured compounds, and display catalytic and magnetic properties. • Zn is not considered to be a transition element as it does not form ions with incomplete d-orbitals. • Transition elements show an oxidation state of +2 when the s-electrons are removed. • Explanation of the ability of transition metals to form variable oxidation states from successive ionization energies. • Explanation of the nature of the coordinate bond within a complex ion. • Deduction of the total charge given the formula of the ion and ligands present. • Explanation of the magnetic properties in transition metals in terms of unpaired electrons.

This is an excellent compilation of all the sub topics IBDP or A level chemistry which I use for all my equilibrium lessons. It has all SL and HL topics clearly covered and in details as appropriate for IBDP. Contents Preview- A state of equilibrium is reached in a closed system when the rates of the forward and reverse reactions are equal. • The equilibrium law describes how the equilibrium constant (Kc) can be determined for a particular chemical reaction. • The magnitude of the equilibrium constant indicates the extent of a reaction at equilibrium and is temperature dependent. • The reaction quotient (Q) measures the relative amount of products and reactants present during a reaction at a particular point in time. Q is the equilibrium expression with non-equilibrium concentrations. The position of the equilibrium changes with changes in concentration, pressure, and temperature. • A catalyst has no effect on the position of equilibrium or the equilibrium constant. • The characteristics of chemical and physical systems in a state of equilibrium. • Deduction of the equilibrium constant expression (Kc) from an equation for a homogeneous reaction. • Determination of the relationship between different equilibrium constants (Kc) for the same reaction at the same temperature. • Application of Le Châtelier’s principle to predict the qualitative effects of changes of temperature, pressure and concentration on the position of equilibrium and on the value of the equilibrium constant. • Free Energy and Equilibrium constant
