Intro to Chemistry and Atoms

Warm Up:Wait for video questions

Homework: 1. Read Section 1.1 of Unit D in Text Answer Q 1-3

Chemistry – The study of matter and atoms and the changes they can undergo

Atoms – The building block and basic unit of all matter- Consist of a small charged particles

Subatomic Particles – Atoms contain charged particles Nucleus Electron Cloud (rings) Positive – Protons Negative – Electrons Neutral – Neutrons

Parts of an Atom :

Nucleus

Electron Cloud

Atomic Number – Number of Protons - This is how elements are arranged on the periodic table

Neutral Atom –Protons = the number of Electrons

Atomic Mass Number – Number of Protons + Neutrons - The total mass of the nucleus

Connection to the Periodic Table of Elements (p. 20 D)

Atomic Number = # of Protons / Electrons

Symbol = 1st letter always capital

Atomic Mass = Protons + Neutrons

Homework:1. Finish Periodic Table Worksheet

- Parts 1 and 2 ONLY

Warm up:

Finish Periodic Table worksheetIntroduction, Organization and History of the

Periodic Table

1. Determine what element this Bohr model is representing.

2. How did you come to this conclusion?

3. Draw a Bohr model for Helium and Neon – can you make any observations that make these two alike in any way?

4. Make a t-chart and compare and contrast mixtures and pure substances.

Matter• Has mass or weight

• Takes up space (volume)•Cannot occupy the same space as other matter at the

same time

Pure Substances• Has the same composition

throughout

• Can Occur Naturally

Mixtures• Formed when two or more substances are

physically combined• Parts can be physically separated

• Substances in a mixture retain their original properties

Element• Cannot be broken down into simper substances

Compound•Chemical combination

of two or more different elements

• Cannot be physically separated

•Properties are entirely different properties of

each element alone

Homogeneous• Parts of the

mixture are evenly distributed

Heterogeneous• Parts of the mixture are not

evenly distributed

Group or Family(All have same number of valence electrons)

Period or Row(One proton is added from left to right)

Metaloids

Nobel Gasses

Non-Metals

Periodic Table Families – Part 3 Metals, Non-Metals and Metalloids

Periodic Table Basics ActivityWarm Up: Identify each container as a beaker full of elements, compounds, heterogeneous mixture or homogeneous mixture.

Finish Periodic Table Basics Activity

Families of Elements on the Periodic Table – Part 3

Properties of ….Metals Metalloids

• Most are solids• Can be shaped &

pulled into wires• Shiny / lustrous• Good conductors

of electricity/heat• Tend to lose

electrons in chemical reactions

• Most are Solids• Can be shiny or

dull• Can be shaped

& pulled into wires

• Conducts better than nonmetals but not as well as metals

•Most are gases•Solid non-metals are brittle•Not shiny, but dull•Poor conductors of electricity and heat•Tend to gain electrons in chemical reactions

Non-metals

History of the Periodic Table

Dimitri Mendeleev (1834 – 1907) • Siberian• Founded the periodic table (1869)• Organized by Atomic Mass and

properties• Could predict where new elements

would go on the table

Henry Moseley (1887-1915)• Studied elements using x-rays• Was able to slightly reposition the

periodic table because he could see protons

• Killed in WWI at age of 28• Britain made a policy that restricts

scientists from fighting in wars

Mendeleev’s Original Periodic Table

Moseley’s Modern Periodic Table
