Valence e-
In VSEPR Theory, the valence electrons are in one of these
What is "a shell?"
A tetrahedron has this many faces
What is four (4)?
amu
What are atomic mass units?
NaCl
Sodium chloride - common table salt
This periodic property decreases as you go across a row of the chart
What is atomic radius?
Electrons do this to each other
What is repel each other?
In a tetrahedral molecule, the central atom is located here with respect to the tetrahedron
What is the center of the tetrahedron?
PV=nRT
What is the Ideal Gas Law?
BaS
Barium sulfide
(Just two elements hanging out as an ionic compound)
There are 5 of them in 0.090120
What are significant figures?
Carbon has this many valence electrons
What is four (4)?
What is at the vertices?
VSEPR
What is Valence Shell Electron Pair Repulsion?
NH4OH
Ammonium hydroxide
(Enter the polyatomics!)
Coke is an example of this kind of matter
What is a homogeneous mixture?
Neon has this many valence electrons
What is eight (8)?
That perfect octet!
The bond angles are sometimes squeezed down to 105° because of this
What is two pairs of un-bonded electrons?
Roy G. Biv
What is "red orange yellow green blue indigo violet?"
(The visible light spectrum)
SF6
Sulfur hexa-fluoride
(Surely you remember how to recognize and name covalent compounds!!)
He is the guy who discovered electrons
Who is JJ Thompson?
A covalent bond is not as repulsive as this
What is an unbonded pair of electrons?
This relatively flat shape based on the tetrahedron can result if there is one double bond
What is the trigonal shape?
STP
What is Standard Temperature and Pressure?
CuCl2
Copper (II) chloride
(Gotta say "Copper-2" because copper is one of those squirrely transition metals!)
This is the most electronegative element in the world
What is fluorine?
