Intro to Chemistry and Atoms
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
Homework:
1. Read Section 1.1 of Unit D in Text Answer Q 1-3
Parts of an Atom :
Electron Cloud
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

C
Carbon
12.001
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

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
Compound
Homogeneous
Heterogeneous
•Cannot be
broken down
into simper
substances
•Chemical combination
of two or more
different elements
•Cannot be physically
separated
•Properties are entirely
different properties of
each element alone
•Parts of the
mixture are
evenly distributed
•Parts of the
mixture are not
evenly distributed
Group or Family

Families of Elements on the Periodic Table – Part 3
Properties of ….
Metals
Non-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 gases
•Solid non-metals
are brittle
•Not shiny, but dull
•Poor conductors of
electricity and heat
•Tend to gain
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

History of the Periodic Table
Periodic Eggs/Atomic Cube Activities
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

Ductility
• The ability of a substance to be
pulled into a wire
Electrical Conductivity: describes how freely
charges can move in a material. Copper is
often used to make wiring because it is ductile
and it has a high electrical conductivity.
