Element’s Name

Atomic Number

Chemical (Atomic) Symbol

Atomic Mass

NOTE: They can be organized different ways. What is an easy way to tell the difference between the

atomic mass and the atomic number??

Page 7: ElementSymbol # of protons # of neutrons # of electron Atomic # Mass # Oxygen8816 SiliconSi141428 AluminumAl141313 Iron2656 Ca202040 BELLWORK: WEDNESDAY.

Atomic Mass = # of protons + # of neutrons

Atomic Number = # of protons

Organized by increasing atomic number

Valence Electrons[Sketch Table ]

An element’s properties can be predicted from its location in the periodic table

Group/Family = column (up/down)# of valence electrons

Almost 75% of all elements are classified as metals

Physical properties of metals:1. hardness 2. luster (shininess)3. malleability (can be

pounded or rolled into shapes or flat sheets)

4. ductility (can be pulled out or drawn into wires)

5. Conductors (transmit heat and electricity easily)

6. Magnetic (attracted to magnets) ex. iron (Fe), cobalt

(Co), and nickel (Ni)

7. Most metals are solids at room temperature (high melting point) Exception: Mercury

(Hg)--liquid at room temperature

elementsMost commonly found

elementsFollows NO rules when

finding valence electrons

Use the two outermost shells/orbitals to bond with other elements Most elements only use

the valence shell

of heat & electricity Are fairly stable,

reacting slowly or not at all with air and water

Most have very high melting and boiling points

Most dissolve in acids (except Gold!)

Most have luster
