Turn in Packet 9. I will be recording grades and passing them back.

QUIZ RESULTS

CYOPT- Create Your Own Periodic Table…

…as well as labeling and taking notes on each group of elements

Charge of atom:

Neutral

Charge of nucleus: Positive

Each square of the Periodic Table usually includes the element’s name, atomic number, chemical symbol, and atomic mass.

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??

READING THE PERIODIC TABLE OF THE ELEMENTS

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

Period = row (left to right)# of orbitals/shells

Begin filling in the atomic symbol, atomic mass, and atomic number for the elements in BIG white PT—be sure to use the same order as the key!

If you didn’t finish the Life Science Vocab in CRT Packet, then it is homework! If you need a book to take home, you may check one out after school.

Complete the table without looking at a periodic table.

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

METALSCYOPT – Write in

the “Metals” Section

GROUP 1: ALKALI METALS

1

Group 11 valence electron

which it readily loses to become a cation

Extremely reactive – NEVER found alone in nature

Only found in compounds, combined with other elements

Reacts violently with water to produce explosions

Causes skin burns if you come into contact with it

Physical Properties: Soft- can be cut with a

plastic knife Shiny Lightweight Good conductors of

electricity and heat Low melting points Tarnishes rapidly

GROUP 1: ALKALI METALS

BELLWORK FRIDAY: 2/24/12

GROUP 2: ALKALINE EARTH METALS

2

Group 22 valence

electrons 2nd most

reactive group of elements in the periodic table

Chemically bond very easily by giving away 2 electrons

Physical Properties:Fairly hardbright whitegood conductors of electricity

high melting pointshigh densities

Why called Alkaline? When mixed in solutions =pH greater than 7Those pH levels are defined as 'basic' or 'alkaline' solutions

GROUP 2: ALKALINE EARTH METALS

3 4 5 6 7 8 9 10 11 12

GROUPS 3-12: TRANSITION METALS

Groups 3-12Largest group of

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

Physical Properties: Most are hard and shiny All are good conductors

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

Lanthanides Actinides

RARE EARTH METALS

Top row (Rare Earth Metals)

Fits in period 6Named after the first

element in the row (Lanthanum)

Physical Properties:SoftMalleableShiny/high lusterHigh conductivity

Found naturally on Earth

Only 1 element in the series is radioactive

RARE EARTH METALS: LANTHANIDES

Bottom row (Rare Earth Metals)

first element in the row (Actinium)

All are radioactiveNucleus is very unstable last for only a fraction of a second after they are made

Some not found in nature Only thorium and uranium exist on Earth in significant amounts

All the elements after uranium were created artificially in the lab

Hydrogen & Helium: full with 2 electrons

Others: full with 8 electronsHappiest elements of all

Will never combine with other elements (too stable)

Colorless, tasteless, & odorless gases

When electricity passes through them, they glow different colors
