LESSON 1.
Reading the Periodic Table
|
Objective:
Students learn to read the periodic table of the elements. |
Materials:
Periodic Table Placemat (Painless Learning
version)
|
Teacher Notes:
This unit reviews the periodic table
emphasizing how to read the table. If your students have not used a
periodic table, the worksheet will help them look in detail at the
different elements.
The periodic table provides information
about the elements including atomic mass, number of protons, families, and
other physical and chemical characteristics. The number of electrons and
neutrons can be calculated from this information. The table is a
chemist's "handbook." Impress on your students that this chart took a
long time to develop. They will read about the history of the periodic
table in Lesson 5.
Students should
appreciate that all substances on Earth are found on this chart. Even
synthetic substances that are produced in the laboratory and not naturally
stable on Earth can be found. The Periodic Table of the Elements should
not be memorized. The more you use the table with your students, the more
the elements become alive.
Please note the
worksheet was designed to work with the recommended Periodic Table
Placemat (Painless Learning). If you are using another Periodic Table you
may have to change some of the questions. |
ANSWERS:
-
gas 11; liquid 4, solid 75; synthetic 22
-
18, the Roman numerals
were an older version
-
7 periods; 6
Period Lanthanide; 7 Period Actinide
-
forest green: alkali
metals; orange: alkaline earth metals; purple: transition metals; blue: other
metals; peach: non metals; yellow: noble gases; bright green: metalloids
Hydrogen is not
represented in the color code as a light green, it is unique
-
Copper (Cu); Silver
(Ag); Tin (Sn); Antimony (Sb); Mercury (Hg); Gold
(Au); Tungsten (W), Iron (Fe), Potassium (K), Lead (Pb), Sodium (Na)
-
Curium (96); Einstenium (99); Fermium (100); Mendelevium
(101); Nobelium (102); Lawrencium (103); Rutherfordium (104); Seaborgium
(106); Bohrium (107); Meitnerium (109)
-
Mercury (80), Uranium
(92); Neptunium (93); Plutonium (94)
-
Cities: Holmium (Stockholm in Sweden, 67); Berkelium
(97); Yttrium (village in Sweden, 39); State: Califorium (98);
Country: Germanium (32); Francium (87), Ruthenium(for Russia, 44);
Americium (95); Polonium (84) Continent: Europium (63)
-
He, Ne, Ar, Kr, Xe, Rn
-
atomic number
-
8; cubic, face centered;
cubic, body centered; cubic; hexagonal; rhombohedral; tetragonal; orthorhombic; monoclinic
-
Uun, Uuu, Uub
-
yes, but there are
exceptions
-
hydrogen, boron, carbon,
nitrogen, oxygen, fluorine, neon, silicon and many more (basically,
groups 17, 18, 14 (exception germanium)
-
the groups seem to have
similar “ballpark” melting and boiling points compared to other groups; some
close elements in periods are very similar (i.e. Co, Ni, Cu)
-
transitional
metals seem to be denser and right side seems to be lighter.
-
s, p, d, f; the period uses the Noble gas
configuration and adds on, each period has similar configuration
-
densest: Osmium (Os, 76)
(22.6); lightest: Hydrogen (H,1) (.071)
-
Boiling Pt. Rhenium (Re,
75) 5596 centigrade; Melting Point: Tungsten (W, 74) 3422 centigrade
(notice that Carbon does not have a boiling point, some consider some of its
isotopes with the highest melting point)…so if you are using a different
table, please note there may be a difference
-
Helium (He, 2) -268.9
centigrade
