Metals

1. Properties of metals Locating metals Properties:________ _________________ All metals have some very similar properties. These properties make metals really useful. Draw a line on the periodic table below to mark out border between the metals and the non-metals. Then label which side is which. Aluminium Uses:_________________ ______________________ 1) Metals are S________ , but can be shaped (m__________) 2) Metals are very good at ___________ heat. Examples: __________________ __________________________ 3) Metals are excellent conductors of __________ . Write the chemical symbol of these metals next to their name, then label them in their correct position on the periodic table: Iron = 4. Magnesium = Copper = 5. Silver = Aluminium = 6. Gold = 4) Metals have high ________ points. Properties:________________________ _________________________________ 5) Metals are normally _______ at room temperature, the one that isn’t is _____________ . Copper Uses:_________________________________ ______________________________________ Examples: ________________________________ _________________________________________ 6) Metals are d______ this means they can made into w____. Properties:______________________________________ _______________________________________________ Iron Uses:______________________________________________ __________________________________________________ Metals Examples: ____________________________________________ _____________________________________________________ Metallic Bonding Electron configuration An element’s atomic number tells you the number of ________ in the nucleus. The number of________ in an atom is equal to the number of _________. How many electrons are there in the elements listed above: 2) 3) 4) 5) 6) In the first shell of an atom there are _____ electrons. In the second shell there are ___ electrons. In the third shell there are ___ electrons. Draw the electrons and their shells onto the atoms below: In a metal, the ________ in the ________ shell are able to move. This is the reason why metals are very good at _____________ h____ and __________. The more __________ in the outer shell, the better the metal is at _____________. In lithium each atom has ____ electron in it’s outer shell. This means that for each atom in a lump of lithium there is one free electron that is able to move around. Potassium No. of electrons = No. in outer shell = + charge in nucleus = Number of electrons per atom free to move= Calcium Lithium Magnesium - Li+ Li+ Li+ Magnesium No. of electrons = No. in outer shell = + charge in nucleus = Number of electrons per atom free to move= Calcium No. of electrons = No. in outer shell = + charge in nucleus = Number of electrons per atom free to move= - - - - Li+ Li+ Li+ - - - Li+ Li+ Li+ -
