start learning

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