|
Students should be able to explain how the reactions of elements are related to the arrangement of electrons in their atoms and hence to their atomic number. |
|
|
|
|
|
The elements in Group 0 of the periodic table are called the noble gases. |
|
Which group of the periodic table are also named the nobel gases? GF: Discuss the relationship between group 0 elements and radioactive decay |
|
|
|
The elements in Group 0 of the periodic table are unreactive and do not easily form molecules because their atoms have stable arrangements of electrons. |
|
Describe in terms of electron structure as to why all of the nobel gases are unreactive Students draw the electronic configuration to work out that they have a full outside shell of electrons |
|
|
|
The noble gases have eight electrons in their outer shell, except for helium, which has only two electrons. |
|
What is the same about the electron structure for all elements in Group 0 (noble gases)? |
|
|
|
The boiling points of the noble gases increase with increasing relative atomic mass (going down the group). |
|
Describe the trend in boiling point down group 0 Investigate the boiling point of group 0 elements and make observations from results |
|
|
|
Students should be able to explain how properties of the elements in Group 0 depend on the outer shell of electrons of the atoms |
|
|
|
|
|
Students should be able to predict properties from given trends down the group. |
