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. Practice Bohr Models2. Finish Pure Substances vs. Mixtures
Graphic Organizer
Warm up:1. Atoms of the same element are alike /
different.2. Protons are positive / neutral / negative.3. Protons are inside / outside the nucleus.4. Neutrons are positive / neutral / negative.5. Neutrons are inside / outside the nucleus.6. Electrons are inside / outside the nucleus.7. The overall charge of the nucleus is
positive / neutral / negative.

Pure Substances vs. Mixtures
Pure Substances – same composition throughout (atoms, elements, compounds)
Mixtures – physical combinations

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
Metals

Homework:1. Finish Periodic Table Basics Activity
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

Moseley’s Modern Periodic Table

Homework:Reflect on 1st Quarter, especially your science grade, and crate a t-chart that lists things you did well with and things you need to improve.
Nuts and Bolts ActivityAnnounced Chemistry Quiz
Warm Up:1) Create a concept map that has the topic of
Chemistry in the middle and branches out into Atoms, Periodic Table, History and Matter. Then expand on each topic.• See below for example:
