CSCOPE Unit 03 Lesson 02 Day 5
Vocabulary
|Group | |a vertical column of elements in the periodic table; also called a family |
| | | |
|Period | |a horizontal row of elements in the periodic table |
| | | |
|Metal | |one of a class of elements that includes a large majority of the known elements; metals are|
| | |characteristically lustrous, malleable, ductile, and good conductors of heat and |
| | |electricity |
| | | |
|Metalloids | |one of a class of elements having properties of both metals and nonmetals |
| | | |
|Nonmetal | |one of a class of elements that are not lustrous and are generally poor conductors of heat |
| | |and electricity; nonmetals are grouped on the right side of the periodic table |
| | | |
|Alkali metals | |any metal in Group I A of the periodic table |
| | | |
|Alkaline earth metals | |any metal in Group II A of the periodic table |
| | | |
|Halogens | |any member of the nonmetallic elements in Group VII A in the periodic table |
| | | |
|Noble gases | |any member of a group of gaseous elements in Group VIII A in the periodic table |
| | | |
|Transition metals | |any element found in the B groups in the periodic table |
| | | |
|Atomic radius | |a way to describe the size of an atom, it is one-half the distance between the nuclei in a |
| | |molecule consisting of identical atoms |
| | | |
|Ionization energy | |the energy required to remove the outermost electron from a gaseous atom |
| | | |
|Metallic character | |the extent to which an element exhibits the physical and chemical properties characteristic|
| | |of metals, high metallic character is associated with low ionization energy |
| | | |
|Electron affinity | |the energy change that accompanies the addition of an electron to a gaseous atom |
| | | |
|Electronegativity | |the tendency for an atom to attract electrons to itself when it is chemically combined with|
| | |another element |
In the first part of today’s CSCOPE you will be labeling a blank periodic table to represent key information.
In the second part of today’s CSCOPE you will need to provide a summary of the historical development of the periodic table.
First Part:
Represent the following information on the blank periodic table on the next page:
metals
nonmetals
metalloids
groups
alkali metals
alkaline earth metals
halogens
noble gases
also…
transition metals
periods
“1” through “7”
trends:
electronegativity
ionization energy
metallic character
atomic radius
electron affinity
Second Part:
In the space provided below the periodic table, write a summary of the historical development of the periodic table. Include dates, names, and their key contribution/s.
