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.
