It means that one end, or one or more parts of the molecule is slightly electrically charged, such that one part of the molecule is positive and another part is negative.
Such a molecule is said to have an electric dipole.
A molecule with opposite charges at opposite ends is said to be a polar molecule. All such molecules are water soluble.
Energy was released when the molecule was formed from its elements
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
As a chemist, I have no idea what "an extra hydrogen molecule in sucrose" is supposed to mean. There is no "extra hydrogen molecule in sucrose".
If a molecule's charges are unevenly distributed its said to be "polar" because the molecule is a bit like a magnet with two poles.
Such a molecule is said to have an electric dipole.
A diatomic molecule is a molecule made up of two atoms.
Such a molecule is said to have an electric dipole.
When a molecule is nonpolar it means there are no charges.
You mean of a fat?
A molecule with opposite charges at opposite ends is said to be a polar molecule. All such molecules are water soluble.
If you use molecule to mean 'tiny piece' then 'whole' would be the antonym.
When you add a hydroxide group to a particular molecule by adding an H2O molecule
A polar molecule has regions of opposing charge. For example in water the hydrogen are in a relatively positive area, as compared to the highly electronegative oxygen. The bent or L-shape to water is because of this polarity.
If you mean "Why is a molecule polarized" it would be because there is a more negative charge to one end of the molecule than the other.
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
