Metallic Bonding and Alloys | IGCSE Chemistry | Cambridge 0620 · Edexcel 4CH1 · OxfordAQA 9202

Metallic bonding, the properties of metals and alloys for IGCSE Chemistry: the sea of delocalised electrons, why metals conduct electricity and heat, why they are malleable and ductile, how metals react with oxygen, water and acids, the uses of aluminium and copper, and why alloys like brass, stainless steel and steel are harder. 📝 Cambridge 0620 notes: Metallic bonding (free): https://www.thinka.ai/en-GB/Cambridge... 📱 Thinka app: practice questions, flashcards and notes: https://www.thinka.ai/en-GB/download?...
