2 PROPERTIES OF METALS Most elements are metals Metals are located left of the Zig Zag lineMetals have few electrons in their outer energy levelMetals are solid at room temperature except Mercury which is a liquid
3 PROPERTIES OF METALSMetals are good conductors of heat and electricityMetals are malleable which means they can be flattened into thin sheetsMetals are ductile which means they can be drawn into thin wiresMetals are shiny
4 EXAMPLES OF METALSGoldSilverMercuryLeadIronNickelCopper
5 PROPERTIES OF NONMETALS Nonmetals are located right of the Zig Zag lineNonmetals have almost a complete set of electrons in their outer energy levelNonmetals are mostly gases at room temperature
6 PROPERTIES OF NONMETALS Nonmetals are not good conductors of heat & electricityNonmetals are not malleableNonmetals are not ductile – they are brittle and will break or shatter when hit with a hammerNonmetals are not shiny
8 PROPERTIES OF METALLOIDS Metalloids are also called semiconductorsMetalloids border the Zig Zag lineMetalloids have a ½ complete set of electrons in their outer energy levelMetalloids have some properties of metals and some properties of nonmetals.
9 EXAMPLES OF METALLOIDS Tellurium-shiny but brittleSilicon-semiconductorBoron-hard but brittle and a good conductor of electricity
10 PROPERTIES OF NOBLE GASES Noble Gases are Family 18Noble Gases have a complete set of electrons in their outer energy level – all but Helium have 8. Helium has 2.Noble Gases are gases at room temperatureNoble Gases are nonmetals
11 PROPERTIES OF NOBLE GASES Noble Gases are colorlessNoble Gases are odorlessNoble Gases are unreactiveNoble Gases are found in very small amounts on Earth
12 EXAMPLES OF NOBLE GASES HeliumArgonKryptonXenonRadon (Radioactive gas)
13 More VocabularyPeriod – a horizontal row of elements on the periodic tableLanthanides – transition metals that follow lanthanum (first row at the bottom). They are shiny, reactive metals. Some are used to make steel.
14 More VocabularyActinides - transition metals that follow actinium (second row at the bottom). They are all radioactive and unstable. They can change into different elements. Elements after plutonium do not occur in nature.
15 More VocabularyFamily – also called a group, are the columns on the periodic table. Most of these elements in a family share similar propertiesMetal – elements that are shiny and are good conductors of thermal energy and electric current; most metals are malleable and ductile
16 More VocabularyNonmetal – elements that are dull and are poor conductors of thermal energy and electric currentMetalloid – elements that have properties of both metals and nonmetals; sometimes referred to as semiconductors.
17 Additional NotesThe number at the top of the block on the Periodic Table is the ATOMIC NUMBER.The ATOMIC NUMBER tells you how many PROTONS are in the nucleus of the atom.The ATOMIC NUMBER is unique to each element.
