Edexcel GCSE Chemistry mock draft, 26–31 Oct. Draft coverage: Chemistry Paper 1 (Higher tier). Reviewed for an original-practice sitting; check student availability before registering. Marking and results will follow later, after separate approval. Eligible new accounts receive a five-day Pro trial when signup email verification completes. Previous trials keep their original expiry. After expiry, new papers need Pro unless you have an explicitly confirmed free sitting offer for this event. That offer adds no Pro time or AI learning. Saved attempts and released results remain readable. No card or automatic charge.

Compare the properties and reactions of Group 1, Group 7, and Group 0 elements. 8 lessons in 1 subtopic.
The noble gases are the Group 0 elements helium, neon, argon, krypton, xenon and radon. The Trends in Noble Gas Properties notes cover this in full.
Halogens are the elements in Group 7 of the periodic table, including fluorine, chlorine, bromine, iodine and astatine. The Introduction to Group 7 Halogens notes cover this in full.
The positive result for chlorine gas is that damp litmus paper is bleached and turns white. The Testing for chlorine as a Group 7 halogen notes cover this in full.
Alkali metals are soft enough to cut with a knife, have low melting points compared to other metals and have low density; lithium, sodium and potassium float on water. The Introduction to Group 1 Elements - The Alkali Metals notes cover this in full.
Noble gases are unreactive because their atoms have stable arrangements of electrons with complete outer shells, so they do not need to gain, lose or share electrons. The Noble Gases: Structure and Unreactivity notes cover this in full.
When potassium reacts with water, it fizzes violently, catches fire immediately with a purple flame and moves very fast. The Introduction to Group 1 Elements - The Alkali Metals notes cover this in full.
A halide is an ionic compound formed when a halogen reacts with a metal, with the halogen as a negative ion such as Cl⁻, Br⁻ or I⁻. The Introduction to Group 7 Halogens notes cover this in full.
When lithium reacts with water, it fizzes gently, moves slowly across the water surface and dissolves. The Introduction to Group 1 Elements - The Alkali Metals notes cover this in full.
