Why is it difficult to wash oil from your hands with plain water?
Both substances are polar. Like polarities repel.
Both substances are nonpolar. Like polarities repel.
Water is nonpolar, and oil is polar, so they will not combine.
Water is polar, and oil is nonpolar, so they will not combine.
Electronegativity is a measurement of the ability of a nucleus to:
attract bonding electrons
attract other nuclei
attract electrons in the non-valence energy levels
Why is the molecule nonpolar?
There are nonbonding pairs on the central atom.
There are different types of elements bonded to the central atom.
There are no nonbonding pairs on the central atom and all of the atoms bonded to the central atom are the same.
Is the following molecule polar or nonpolar?
polar
nonpolar
Why is the molecule polar?
There is a nonbonding pair on the central atom.
There are different types of elements bonded to the central atom.
There are no nonbonding pairs on the central atom and all of the atoms bonded to the central atom are the same.
When two atoms of the same nonmetal element bond together, they form a(n)
ionic bond.
nonpolar covalent bond.
polar covalent bond.
James Bond.
In order to determine if a molecule is polar, you must consider the
polarity of bonds and symmetry of the molecule.
number of electrons and number of bonds.
polarity of bonds only.
total charge of each ion and number of multiple bonds.
Polar molecules have
no charges.
slight positive and negative charges on opposite ends of the molecules.
only positive charges.
either positive or negative charges, but not both.
