that make up an atom and where are they located?

Homework: New Notebook Friday 10/18

Families on the Periodic Table• Elements on the periodic table can be

grouped into families bases on their chemical properties.

• Each family has a specific name to differentiate it from the other families in the periodic table.

• Elements in each family react differently with

• other elements.

ALKALI METALS

• Group 1• Hydrogen is not a

member, it is a non-metal• All are metals and solid at

room temp• 1 Valence Electron• Soft and silvery, shiny• Very reactive, esp. with

water• Conduct electricity

ALKALINE EARTH METALS• Group 2• Metals• Be,Mg,Ca,Sr,Ba,Ra• Solids at room

temp• 2 electrons in the

outer shell• White, silvery, and

malleable• Reactive, but less

than Alkali metals• Conduct electricity

TRANSITION METALSMetalsAlmost all are solids

at room temp (Hg)Good conductors of

heat and electricity.1 or 2 Valence

ElectronsLess Reactive than

Alkali and Alkaline Earth

Can bond with many elements in a variety of shapes.

BORON FAMILY

• Group 3• 3 (valence)electrons

in the outer shell• Most are metals• Boron is a metalloid

all other elements are metal.

• Reactive• Solid at room temp

CARBON FAMILY • Group 4• 4 (valence)

electrons in the outer shell

• Contains 3 metals (Fl, Pb, Sn), 2 metalloids(Si, Ge), and 1 non-metal Carbon (C)

• Reactivity varies• Solids at room

temp

NITROGEN FAMILY • Group 5• 5 electrons in the

outer shell• Can share electrons

to form compounds• Contains 2

metals(Bi,Sb) , 2 metalloids(As,’Pb), and 2 non-metals(P,N)

• Reactivity Varies• Nitrogen is the only

gas at room temp, rest are solids

OXYGEN FAMILY • Group 6• 6 electrons in

the outer shell• Contains 2

metals(Po,Lv), 1 metalloid(Te), and 3 non-metals(O, S, Se)

• Reactive• Oxygen is a gas,

the rest are solids at room temp

Halogens• Group 7• 7 electrons in

the outer shell• Non-metals, Uus

is unknown• Very reactive -

are often bonded with Group 1 Alkali Metals

• Has 2 gases(F, Cl), 1 liquid (Br), and 2 solids

Noble Gases• Group 8Exist as gasesNon-metals8 electrons in the

outer shell = FullHelium (He) has

only 2 electrons in the outer shell = Full

Not reactive with other elements

Rare Earth MetalsSome are

RadioactiveThe rare earths

are silver, silvery-white, or gray metals.

Conduct electricity

Week #1 Quarter 2 (10/18)

To Do Today:•Check for notebook •Discuss Lewis Dot structure and Bohr Model of atomic diagrams

Fact of the DayCarbon is most commonly obtained in coal deposits. Diamonds are found in volcanic rock, called kimberlite, located in South Africa, Arkansas, and elsewhere. Name is Latin for charcoal.

Today in I.S.…I.S. Learning Goal:•I can describe the features and components of the atom. •I can apply models to features of an atom

Warm Up Question: Why is carbon important in the study of organic chemistry?

Homework: notebook cover Monday Notebook set up Monday

Periods •Each row is called a “period”

1st Period = 1 Shell

2nd Period = 2 Shells

3rd Period = 3 Shells

4th Period = 4 Shells

•The elements in each period have the same number of shells

Periodic table of elements video http://www.brainpop.com/science/matterandchemistry/periodictableofelements/

Groups

•Each column is called a “group”

•Each element in a group has the same number of electrons in their outer orbital, also known as “shells”.

Group 1 = 1 electron

Group 2 = 2 electrons

Group 8 = 8 electronsExcept for He, it has 2 electrons

•The electrons in the outer

shell are called “valence electrons”

Transition Metals•Transition Metals have slightly different rules for shells and valence electrons.

Lewis Structures1) Find your element on the periodic table.

2) Determine the number of valence electrons.

3) This is how many electrons you will draw.

Put onto back of “Find that Element!” handout

21

Lewis Structures• Find out which group

(column) your element is in.• This will tell you the number

of valence electrons your element has.

• You will only draw the valence electrons.

22

Groups - Review

•Each column is called a “group”

•Each element in a group has the same number of electrons in their outer orbital, also known as “shells”.

Except for He, it has 2 electrons

•The electrons in the outer shell are called “valence electrons”

Order of How to Draw Lewis Dot Structures

23

24

Lewis Structures1) Write the element

symbol.

2) Carbon is in the 4th group, so it has 4 valence electrons.

3) Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol.

25

Lewis Structures1) Check your work.

2) Using your periodic table, check that Carbon is in the 4th group.

3) You should have 4 total electrons, or dots, drawn in for Carbon.
