Valence Shells
How many electrons does the first shell hold?
2
What range of electronegativity difference does a compound have to be to be considered Polar?
0.40 and above
What intermolecular force is the strongest?
Hydrogen Bonding
What is my first name + correct spelling
Karah
How many valence electrons does Bromine have?
7
What is the most AND the least electronegative atoms on the periodic table?
Fluorine + Francium
What intermolecular force applies to two nonpolar molecules?
London Dispersion Forces
What is Ms. Andrews' dog's name?
TRUE OR FALSE: the number of valence electrons affects the electronegativity of an atom.
False
What partial charge is assigned to the more electronegative atom in a bond?
Partial Negative
What is Dipole-Induced Dipole force?
What is Ms. Andrews' favorite color?
Purple
Why does Hydrogen only want a total of 2 valence electrons?
Because it only has the first electron shell, which holds a maximum of 2 electrons instead of the standard 8.
Why do nonpolar molecules evaporate faster than polar molecules?
Polar molecules have strong intermolecular forces, so they stick together more strongly and are harder to break apart.
Rank all four intermolecular forces from strongest to weakest.
Hydrogen Bonding, Dipole Dipole, Dipole induced Dipole, London Dispersion
What does Like - Dissolves - Like mean?
Like substances will dissolve like substances. Polar substances will dissolve polar substances.
As an atom gains more electron shells, the electronegativity will
decrease
Coloumbs Law: What are the two variables that affect electronegativity?
Distance from the nucleus (number of electron shells) and the number of protons.
Give an example of a mixture containing two molecules where Dipole-Induced Dipole forces would apply.
A polar and a nonpolar molecule example.
__________ is a molecule's ability to stick to itself.
Cohesion
