Which scenario is most likely to result in a polar covalent bond?
Atoms with very different electronegativities
What is the role of electronegativity in predicting how atoms will form bonds?
Helps predict if atoms will share electrons equally
In a polar covalent bond, which atom will be slightly more negative?
The more electronegative atom
How are electrons shared in a nonpolar covalent bond?
Equally between the two atoms
What is the key characteristic of an ionic bond?
Exchange of electrons
How do partial charges affect the polarity of a molecule?
They generate opposite poles in the molecule
What happens to the middle of a rope if one person is stronger than the other?
It moves towards the stronger person
What does it mean for a covalent bond to be polar?
The electrons are shared unequally
How does the electronegativity of an atom affect its charge in a polar covalent bond?
It creates partial charges
What can be said about electron clouds in atoms?
'Orbitals' are predictions of electron location
