Alkali Metals Brainiac Alkali Metals Video 1st column on the periodic table (Group 1) not including hydrogen. Group Contains: Metals Other Information: Electrons in the Outer Shell Most Reactive, So reactive (Valence Electrons): 1 that in nature these are only found combined with other Reactivity: VERY Reactive elements Other Shared Properties: Softness, Color of silver, Shiny, Low density Alkaline-Earth Metals Alkaline Earth Metals Video 2nd column on the periodic table (Group 2) Group Contains: Metals Electrons in the Outer Shell (Valence Electrons): 2 Reactivity: VERY Reactive, but not as reactive as alkali metals Other Shared Properties: Color of silver, higher densities than alkali metals Transition Metals Transition Metal Video Columns 3-12 on the periodic table Lanthanides: Shiny, Other Information: Group Contains: Metals reactive metals, some Lanthanides andused to make steel Actinies: 2 rows Electrons in the Outer Shellat (Valence Electrons): 1 or 2 bottom of periodic Actinides: radioactive table Less to keep table (unstable) Elements after Reactivity: reactive than from being toooccur wide. plutonium do not in alkaline-earth nature in similar a lab) Each(created row has metals properties Other Shared Properties: Shininess, good conductors of thermal energy & electric current; higher densities & melting points than elements in groups 1 and 2 Boron Family Boron Family Video 13th column on the periodic table (Group 13) Other Information: Metalloid Group Contains: Aluminum is 1the most 4 Metals common & most abundant Electrons in the Outer Shell in earth’s crust. (Valence Electrons): 3 USES: Aircraft parts, auto parts, siding, foil, cans Reactivity: Reactive REACTIVE? Thin layer Other Shared Properties: aluminum oxide form s on surface when temperature reacts w/ Solids at room oxygen. Prevents further reaction. Carbon Family 14th column on the periodic table (Group 14) 1 Nonmetal Information: GroupOther Contains: 2 metalloids Nonmetal: carbon found metalsand uncombined in2nature Electrons in the Outer Shell forms wide variety of (Valence Electrons): 4 compounds. Metalloids used to make Varies among the Reactivity: computer elements chips in the group Other Sharednot Properties: Tin useful very reactive Solids at room temperature Nitrogen Family Boron, Carbon and Nitrogen Family Video 15th column on the periodic table (Group 15) Group Contains:2 Nonmetals Other Information: 2 metalloids Nitrogen makes1 up 80% of metals airinwe Electrons the breathe Outer Shell (Valence Electrons): Phosphorous is extremely 5 reactive. Only found Varies among the Reactivity: combined with other elements in the group elements in nature Other Shared Properties: Solids at room temperature Except Nitrogen (N) which is a gas Oxygen Family Oxygen Family Video 16th column on the periodic table (Group 16) Group Contains: 3 Nonmetals 1 metalloid Other Information: 1 metal Oxygen 20% Shell of air Electrons in theisOuter SulfurElectrons): commonly (Valence 6 found: Yellow solid in nature & Reactive Reactivity: Used to make sulfuric acid Other Shared Properties: All but oxygen are solid at room temperature Halogens Family Comparing Halogen Family Video 17th column on the periodic table (Group 17) Information: Nonmetals GroupOther Contains: Very reactive Electrons the Outer Shellother Combineinreadily with (Valence atoms, Electrons): especially7metals to gain the missing electron Reactivity: Very Reactive Halogen + Metal = salt Chlorine andProperties: iodine used as Other Shared Poor Conductors of electric current, violent reactions with alkali metals to form disinfectants salts; never in uncombined form in nature Similar chemical properties but physical properties among halogens can be very different Noble Gases Family Noble Gases Family Video 18th column on the periodic table (Group 18) Other Information: Nonmetals Group FullContains: set of electrons in the outer shell Electrons in the Outer Shell (Valence Electrons): 8 Under normal conditions, Except Helium which has 2 Reactivity: unreactive Unreactive Other Shared UsefulProperties: because of Colorless, odorless gases at unreactivity: Lightbulbs, room temperature Helium, Neon Signs Hydrogen 1st Element in 1st column on the periodic table Other Information: Because of properties, it doesn’t fit with other groups Electrons in the Outer Shell 1 atoms (Valence Electrons): Located above group 1 because of alkali metals also have only one electron in outer level Reactivity: Reactive Physical properties like those of Other Shared Properties: nonmetals Colorless, odorless gases at Found in Stars room temperature; low density; Most abundant Element explosive reactions with oxygen Reactive nature makes it useful in rocket fuel Periodic Table Elements Song of the Elements http://www.elife-pharmacy.com/?aff=10046
