Unit 4.5: Use electronegativity to identify polarity of the bond Flashcards
4.5 Lecture Notes
Electronegatvity (increases/decreases) across periods on the periodic table.
Increases
4.5 Lecture Notes
The ability of an atom in a molecule to attract electrons to itself
Electronegativity
4.5 Lecture Notes
Electronegatvity (increases/decreases) down rows on the periodic table.
Decreases
4.5 Lecture Notes
What does electronegativity have the same trend as?
Effective nuclear charge
4.5 Lecture Notes
What does electronegativity have the opposite trend as?
Atomic size
4.5 Lecture Notes
What do electrostatic potential maps do?
Visualize the distribution of the electrons in a bond.
4.5 Lecture Notes
Covalent bonding between two unlike atoms results in (equal/unequal) sharing of the electrons.
Unequal
4.5 Lecture Notes
In a polar covalent bond, the end with the larger electron density gets a partial (positive/negative) charge.
Negative
4.5 Lecture Notes
In a polar covalent bond, the end that is electron deficient gets a partial (positive/negative) charge
Positive
4.5 Lecture Notes
Created when there is an unequal sharing of electrons between atoms.
Bond Dipole
4.5 Lecture Notes
A molecule that shares electrons equally has (polar/nonpolar) covalent bonds.
Nonpolar
4.5 Lecture Notes
A molecule that shared electrons unequally is (polar/nonpolar).
Polar
4.5 Lecture Notes
The bond dipole moment vector points towards the (negative/positive) end of the bond.
Negative
4.5 Lecture Notes
On the lewis structure, the atom with the most electrons is partially (negative/positive).
Negative
4.5 Lecture Notes
A bond with a large electronegativity means it has a (large/small) dipole moment.
Large
