I am a GCSE and A-level Chemistry specialist teacher in a 14-18 school with 15 years teaching experience and several years research experience. I provide GCSE, AS and A2 Chemistry resources (mainly for the AQA specifications) to help students practice the concepts learned in lessons and I am a firm believer in 'Practice makes perfect'. I strive wherever possible to include the answers to the worksheets.

GCSE Chemistry Structure and Bonding Questions (Sticky Labels)
hf583hf583

GCSE Chemistry Structure and Bonding Questions (Sticky Labels)

(0)
The four files listed contain 4 different questions to assess learning of the fundamentals of Structure and Bonding. They are set up to be printed on 21 labels per page sticky label sheets. These can be used in conjunction with diagnostic homework - for example, if students have incorrectly answered a question on ionic or covalent bonding, these can be used to supplement and reinforce any corrections to be made upon student feedback. Bonding 1 looks at basic bonding questions for ammonia and Bonding 2 does the same for lithium fluoride. Bonding 3 asks students to draw the electrons arrangements for the atom and then the ion formed, working out the charges the ions end up with. Bonding 4 requires students to explain and describe the type of bonding in different substances.

This worksheet contains questions covering the four general word equations for neutralising acids, naming salts, identifying the other products of neutralisation (water, hydrogen or carbon dioxide), identifying gases, salts, acids, alkalis and bases from equations, and practice at writing the ionic formulae of salts and metal carbonates.
AS and Year 1 Free-radical substitution Mechanisms Revision - Lollipanisms (Lollipop Mechanisms)
hf583hf583

AS and Year 1 Free-radical substitution Mechanisms Revision - Lollipanisms (Lollipop Mechanisms)

(0)
A revision activity for learning and practicing free-radical substitution reactions. The above resources are needed along with a set of lollipop sticks. The stickers document contains 3 halogens (fluorine, chlorine and bromine - labelled as A, B and C) and 10 alkanes/halogenoalkanes (labelled 1 to 10) for the halogen to react with. Each pair or group of students should have a set of lollipop sticks containing 9 sticks with halogens printed or written on them (3 of each halogen) and one each of the 10 alkanes/halogenoalkanes. The sticks could be colour coded by adding a stripe of colour or washi tape around the top edge for ease of seeing. Students pick one halogen and one alkane/halogenoalkane and write the full mechanism including the initiation, propagation and termination steps. The answers are provided on 8 answer sheets which are set up to be printed on sticky labels (4 per sheet) or directly onto card to be cut up into A6 size. The cards could be ring bound (30 cards in total) to give one complete set of answers (A1-A10, B1 -B10 and C1-C10). Students can self-assess their answers. All combinations of answers included.
