Topic 13.1: Trends across period 3

13.1.1 Explain the physical states (under standard conditions) and electrical conductivity (in the molten state) of the chlorides and oxides of the elements in period 3 in terms of their bonding and structure

13.1.2 Describe the reactions of chlorine and the chlorides referred to in 13.1.1 with water

Topic 13: Periodicity

Topic 13 of the IB HL Chemistry syllabus is the Periodicity. IBO recommends to spend 4 hours on this topic.

This topic has 2 sub-chapters: "Trends across period 3", and "First-row d-block elements". Each are separated with numerical values in order of mentioned.

These are advanced HL syllabus statements, it is recommended to bring a Casio Graphical Calculator instead of Texas. Casio Calculators have the periodic table installed already.
