ICSE Class 10

Chemistry

Free, interactive Chemistry lessons for ICSE Class 10, written to the syllabus and built to be worked through rather than skimmed.

Chemistry is where a lot of ICSE Class 10 students lose marks they did not need to lose — not because the ideas are hard, but because the definitions have to be exact and the trends have to be explained rather than recited. An answer that says an atom “gets bigger” earns nothing; one that says the number of shells increases down a group, so the outermost electron is further from the nucleus, earns the mark.

Each lesson below takes one idea, builds it from what you already know, and then makes you use it. You answer as you read and check yourself immediately, so a misunderstanding surfaces in the lesson rather than in the exam. When you have finished, download a print-ready PDF with your answers filled in and use it for revision.
