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