Periodic Table
A) The early periodic table
1) What created a need for the first periodic table?
2) Dmitri Mendeleev –
3) How did Mendeleev organize his periodic table?
a) Group4) What was so revolutionary about Mendeleev’s table?
B) Moseley and the periodic law
1) How did Mosley reorganize Mendeleeves table?
2) The Periodic Law -.
6-2 Reading the Periodic Table
A) What is the periodic table of the elements?
1) What is the periodic table?
2) What is the largest naturally produced element?
3) What made all the elements?
4) What can be inferred from an elements location on the periodic table?
B) How are elements squares organized on the periodic table?
1) Groups or Families –
a) Elements in the same groups have similar chemical properties because these elements have the same
number of valance electrons which are the electrons involved in bonding
b) Because groups or families have similar chemical properties some have been given special names
c) Alkali metals:
(I) Group
(II) Origin of name
d) Alkaline earth metals
(I) Group
(II) Origin of name
e) Halogens
(I) Group
(II) Origin of name
f)
Nobel gas
(I) Group
(II) Origin of name
Group names of elements
Transition Metals
C) Are there different types of elements?
1) An element can be classified as one of three basic types, Metals, Nonmetals, and Metalloids or
Semimetals
2) In general metals occupy the left side of the periodic table, nonmetals are on the right side of the periodic table,
and metalloids separate them in a “magical
stairway shape”
The periodic table separates elements into regions of metals non metals and metalloids
3) Metals:
a) Physical properties of metals:
(I) Luster-
(IV)
(II) Malleable -
(V)
(III)
b) Chemical Properties of Metals:
(I)
(II)
4) Nonmetals:
a) Physical properties of nonmetals:
(I)
(II)
(III)
(V)
(IV)
b) Chemical Properties of Nonmetals:
(I)
(II)
5) Metalloids:
a) Physical Properties of Metalloids:
(I) Metalloids can be shiny or dull
(II) Metalloids conduct heat and electricity better than nonmetals but not as well as metals
(III) Metalloids can be dense or light weight
(IV) Metalloids have a melting point between metals and non metals
(V) Metalloids can be malleable or brittle
6-3 Trends in the Periodic Table
A) What can the periodic table tell us about an elements physical and chemical characteristics?
1) As you scan from left to right on the periodic table numerous physical and chemical characteristics become
described in trends
a) There are 3 main atomic trends described by the periodic table:
(I)
(II)
(III)
B) How does the periodic table describe an elements atomic radius?
1) Atomic radius a) Why is atomic radius so important?
b) What happens to an atoms hold on electrons as it gets bigger?
c) What is the trend for atomic radius moving across a
period?
d) What is the trend for atomic radius moving down a family
or group?
C) How does the periodic table describe Ionization energy?
1) Ionization energy -
2) What would a high ionization energy infer about an atom? A
low ionization energy?
3) What is the trend for ionization energy moving across a
period?
4) What is the trend for ionization energy moving down a family or group?
5) How does ionization energy relate to atomic
radius?
6) Explain the irregularities in ionization energy:
D) What is electronegativity?
1) Electronegativity -
2) What is the trend for ionization energy moving across a period?
3) What is the trend for ionization energy
moving down a family or group?
4) How does ionization energy relate to atomic
radius?
