Chemistry: Bonding, structure and properties of matter 5.0 / 5 based on 1 rating ? ChemistryStructure and bondingGCSEAQA Created by: NazrafCreated on: 16-10-17 19:12 What does ionic bonding occur between? Metals and non-metals 1 of 12 Metals are... Lustrous, solid, dense, usually strong, malleable, good conductors of electricity and heat and sonorous 2 of 12 What metals are magnetic? Iron, nickel and cobalt 3 of 12 Non-metals are... Dull, gas,light, weaker, brittle and good insulators off eelctricity and heat 4 of 12 What are ions? Electrically charged particles found, formed when atoms gain or lose electrons 5 of 12 What does diatomic mean? Two atoms - for example, gases are diatomic (O2) 6 of 12 What ions do metals form? Positive (they lose electrons) 7 of 12 What ions do non-metals form? Negative (they gain electrons) 8 of 12 What are ionic bonds? The electrostatic forces of eelctrion between oppositely charged ions 9 of 12 What is a lattice? A 3D structure formed from atoms held by ionic bonds 10 of 12 Properties of ionic substances: (sodium chloride) Form shiny crystals, very hard, high melting point, soluble and will conduct electricity if molten or liquid 11 of 12 Properties of covalent substances: (water) Smooth, soft, low melting point, insoluble and won't conduct electricity 12 of 12
