IRP Check-in

5. What are synthesis and decomposition reactions?

1.1

Relate an atom’s electron configuration to its Periodic Table row and group.

1.1B *Extension: Investigate the s, p, d and f blocks of the Periodic Table.

1.2 Describe trends in reactivity and metallic character across a row and down a group on the

Periodic Table, and so predict those properties for a given element.

1.3

Define ‘isotope’ and ‘radioisotope’ and give examples.

1.4

Explain that natural radioactivity arises from the decay of

nuclei in atoms, releasing particles and energy.

1.5

Identify examples of the medical and industrial use of nuclear

5.1 Carry out decomposition reactions and write word equations

5.1B *Extension: Write symbol equations

Equations

Writing word equations for synthesis and decomposition reactions

6. When do precipitation reactions occur?

6.1 For soluble, insoluble, aqueous, solution, precipitate:

a. define the terms

b. draw and interpret diagrams to explain them.

6.2 Conduct experiments and write word equations for precipitation reactions.

6.3 Given solubility rules, predict whether or not a precipitate will form in a reaction between ionic solutions.

6.3b *Extension: Describe what soluble and insoluble substances look like when placed in water, and explain in terms of the actions of their ions.
