Chapter 3 Flashcards
What is the equation for the ozone formation?
Energy + 3 O2 = 2 O3
What must be absorbed for Energy + 3 O2 = 2 O3 reaction to occur?
Energy because it has to be endothermic
What is an allotropic?
2 or more forms of the same element that differs in chemical structure and therefore their properties
Ozone is what form of oxygen?
Allotropic
Where is the troposphere?
Where we live
What is the stratosphere?
The Ozone layer
Where is atmospheric pressure highest?
Closer to the sea level
How does ozone increase?
From pollution
What are valence electrons?
The electrons in the outermost energy levels
What are valence electrons responsible for
Responsible for chemical bond formations
What tells you the number of valence electrons on the periodic table?
The group number
How many groups are there on the periodic table?
8 groups (1-8)
Who developed a method of visual representation for the valence electrons?
G.N. Lewis
What represents the valence electrons?
Dots around the symbol of an atom
Whats the octet rule?
In chemical reactions, atoms tend to gain, lose or share electrons so to have 8 valence electrons
