spørsmålet		svaret
What type of bonding is found in metals? begynn å lære		Metallic bonding
What is metallic bonding? begynn å lære		The strong electrostatic attraction between positive metal ions and delocalised electrons.
Why do metals conduct electricity? begynn å lære		Delocalised electrons are free to move and carry charge.
Why do metals have high melting and boiling points? begynn å lære		Strong electrostatic forces between ions and delocalised electrons need lots of energy to overcome.
Why are metals malleable? begynn å lære		Layers of atoms can slide over each other without breaking the bonding.
What is an alloy? begynn å lære		A mixture of two or more elements, usually metals
Why are alloys harder than pure metals? begynn å lære		Different-sized atoms disrupt the layers so they cannot slide easily.
What is steel mainly made from? begynn å lære		Iron and carbon.
