metals are used in many everyday objects this morning when I woke up I cited to have a soft-boiled egg and a cup of coffee the pot I used is made of metal the kettle is made of plastic but the coil heating element inside it is made of metal metals are good conductors of heat this is the reason why metals are used to make these every day objects you would never see a pot made of wood or heating element made of plastic metals are also good conductors of electricity The Wire finger Kettle to the electrical socket is actually made of many copper wires insulated with a layer of rubber think about the shapes everyday objects we described the pot the heating element inside the cattle and the copper wires notice that they are very metals are malleable this means that they can be molded into different shapes metals are very ductile this means that they can be into wires  to fully understand these properties of metals we must understand metallic bonding when we talk about bonding we are actually describing the electrostatic attraction between the metal ions arranged in a lattice structure and the free-floating electrical runs around them  since these electrons are free to move around the term sea of electrons is also used what is a lattice structure and where have you heard this term before let's pause the lesson to think about this and resume when you are done the term lattice structure means that there is a regular repeating pattern we have heard this turn before when discussing glad to seize it is used to describe the alternating positions of the metal and non-metal ions in metallic structures however they're only metal ions these metal ions are arranged side-by-side in a regular repeating pattern the free-floating electron act like a glue and hold the structure in place this is a very strong attraction and explains why metals have high melting boiling points a lot of heat energy is needed to overcome this attraction  this is also why metals are very good stars of heat  free floating electrons are the reason why metals can conduct electricity metals are malleable and because no matter what shape the metal takes the free-floating electrons will conform to that shape the strong electrostatic attraction will remain and therefore the structure stays intact let's think about it cars and bicycles trains planes buildings Cutlery spectacle furniture and endless items can be made from metals  to recap the electrostatic attraction between metal ions arranged in a how to structure and free-floating electrons is known as metallic bonding this explains many properties of metals they are good conductors of heat and electricity have high melting and boiling points and are malleable and ductile
