  • Element NotesElements are the basic substance from which all matter is made.

  • Element NotesAn element is a basic substance that cannot be broken down during chemical reactions.

  • Element NotesThere are 90 naturally occurring elements, and 25 synthetic (man made) elements on Earth. Most are not in their pure form.

  • Element Notes Elements combine to make all the substances on Earth.

  • Element NotesAll elements have properties.

  • Element NotesElements can combine to form different substances with properties different than the elements from which they are made.

  • Element NotesSome elements are common, some elements are rare.

  • Element NotesThe periodic table of elements displays all of the naturally occurring and synthesized (man-made)elements.

  • Element Notes Each element has a name and is represented by a one or two letter symbol in the table. The first letter is always capitalized; the second letter is always lower case.

  • Element Notes Some of the elements have a single letter for a symbol. The single letter is ALWAYS capitalized.

    These are generally the very common ones such as oxygen, hydrogen or carbon.

  • Elements Some element symbols can be confusing such as Na for sodium, K for potassium, Fe for iron, Au for gold, and Ag for silver.

    This is because they come form latin.

  • Elements

    Some elements are named after people or placesYtterbium Y, Ytterby a village in SwedenRutherfordium (Rf), Ernest Rutherford.Lead (Pb), Plumbum, Latin word

  • Mendeleev's Periodic Table...

  • Today's Periodic Table...

  • Mendeleev our Main Man! constructed a table which 'house' elements by characteristic properties some elements were not even discovered then, he left 'gaps' in his table for eventual discovery - cool isn't it

  • Dmitri Ivanovich Mendeleev(1834-1907)

    Organized elements increasing atomic mass Noticed that there was a repetition or periodic pattern in their properties.

  • Classifying the Elements

    MetalsAll elements to the left side (except H) of the stair-step line from B to At

  • MetalsAll elements to the left side (except H) of the stair-step line from B to Atgood conductor of heat and electricityshiny lustersolid at room temperature (except Hg)Malleable and ductilehigh boiling and melting pointsHigh densities

  • Non- Metals

    Occupy the upper right side of the periodic table (right of the stair-step line from B to At)

  • Non-Metals (Characteristics)Generally gasses at room temperature Poor conductors of heat and electricity Brittle dull-looking when solidshigher boiling and melting points (except carbon) usually have lower densities than metals

  • Metalloids

    Elements border the stair-step line from B to AtPhysical and chemical properties of both metals and non-metals

  • The Modern Periodic TableGroupsThe boxes are arranged in order of increasing atomic number in a series of columns called groups or famlies.

  • The Modern Periodic TableGroupsEach group is numbered 1 through 18,.

  • Alkali MetalsThe chemical elements that are identified as alkali metals are lithium, sodium, potassium, rubidium, cesium, and the extremely rare radioactive substance called francium. They occupy the first column of the periodic table of the elements .

  • Alkali MetalsAlkali Metals are in group because they all have one valence electron (one electron in its outer most energy level).

  • Alkali MetalsPhysical properties:Densities are lower than other metalsGood conductors of electricityShiny, soft, malleable. Do not exist free in nature

  • Alkali metalsChemical properties:Most Reactive group of elements on the Periodic TableVery highly reactive (must be stored in oil to prevent reaction with air)http://www.youtube.com/watch?v=Ft4E1eCUItIhttp://www.youtube.com/watch?v=m55kgyApYrY&feature=related

  • Alkali Earth Metals

    The members of the alkaline earth metals include: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Second most reactive group of elements on the Periodic TableAlkaline Earth Metals have two valence electronshttp://www.youtube.com/watch?v=DFQPnHkQlZM

  • Halogens

    In the second column from the right side of the periodic table, you will find Group Seventeen (Group XVII). This column is the home of the halogen family of elements. Who is in this family? The elements included are Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), and Astatine (At). Halides are very reactive.. Halides contain seven valence ekectrons.

  • Halogens

    Fluorine is actually the most reactive and combines all of the time. As you move down the column, reactivity decreases.

  • Noble Gases

    Also called INERT GASES Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). This family of elements do not react with other elements.Noble Gases have 8 valence electronsYou will find inert gases all over our world. Neon is used in advertising signs. Argon is used in light bulbs. Helium is used to cool things and in balloons. Xenon is used in headlights for new cars.

  • Hydrogen

  • Hydrogen

    Hydrogen is the first element in the periodic table and the most basic and common of all elements in the universe. Over ninety percent of all the atoms in the universe are hydrogen atoms and they are the lightest of all elements. Hydrogen will react with almost all other elementshttp://www.youtube.com/watch?v=fesgl5Cs5FY
