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