Study Notes

Locations of Elements on the Periodic Table

Metals occupy the middle section and are positioned to the left of the stair-step line.
Metalloids are found to the right of the stair-step line and to the left of nonmetals.
Nonmetals are located on the far right side of the table, past the zig-zag line.

Characteristics of Metals

Ductile and malleable, allowing them to be drawn into wires or hammered into sheets.
Excellent conductors of heat and electricity.
Generally appear shiny in appearance.

Characteristics of Nonmetals

Lackluster or dull in appearance (not shiny).
Poor conductors of heat and electricity.
Not ductile or malleable.

Development of the Periodic Table

The first periodic table was created by Dmitri Mendeleev, organized by increasing atomic mass.
The modern periodic table was developed by Henry G.J. Moseley, based on increasing atomic number.

Families of Elements

Noble Gases (Group 18): Known for their non-reactivity due to having 8 valence electrons.
Alkali Metals (Group 1): Extremely reactive with one valence electron, typically not found in nature.
Alkaline Earth Metals (Group 2): Very reactive with two valence electrons, less so than alkali metals.
Transition Metals (Groups 3-12): Includes metals with variable valence electrons.
Boron Group (Group 13): Contains 3 valence electrons and is somewhat reactive.
Carbon Group (Group 14): 4 valence electrons, includes metals, metalloids, and non-metal carbon.
Nitrogen Group (Group 15): Holds 5 valence electrons with varying reactivity; tends to gain 3 electrons.
Oxygen Group (Group 16): 6 valence electrons and reactive, tends to gain 2 electrons.
Halogens (Group 17): Contains 7 valence electrons, extremely reactive, and typically never found uncombined in nature.

Significant Elements and Their Properties

Gold's chemical symbol is Au.
Hydrogen is the only element that has no neutrons.
Mercury (Hg) is a transition element and is liquid at room temperature.
Bromine (Br) is the only halogen that is a liquid.

Valence Electrons and Reactivity

Alkali Metals: 1 valence electron, very reactive and soft with a shiny silver color.
Alkaline Earth Metals: 2 valence electrons, reactive but less so than Group 1, also silver in color.
Boron Group: 3 valence electrons, somewhat reactive.
Carbon Group: 4 valence electrons, can either give away or take electrons, includes various types of elements.
Nitrogen Group: 5 valence electrons, reactivity is variable.
Oxygen Group: 6 valence electrons, reactive.
Halogens: 7 valence electrons, seek to gain one electron to complete their shell.
Noble Gases: 8 valence electrons, non-reactive and characterized as colorless and odorless gases at room temperature.
