A molecule is the smallest particle of a substance (material or "matter") that retains its characteristic chemical identity - e.g. texture, colour-, physical properties - behavior as a solid, liquid, gas or other state at different temperatures and pressures - and its chemical properties - how it reacts with other substances.
A molecule may be as small as a single atom of an element - elements as found in the periodical table, e.g. helium atoms, gold atoms - or may be a structure of several atoms linked to one another. For example, a molecule of water is two hydrogen atoms connected to one oxygen atom.
Some molecules may be very large and geometrically complex, such as the molecules - like DNA, proteins and other organic compounds - that make up living systems.

∙ 11y agoA molecule is 2 or more atoms bonded to form a "compound' with it's own unique chemical properties. Bonds increase stability.
A molecule of water is comprised of 2 Hydrogen atoms and one Oxygen atom.
A molecule of Oxygen is comprised of 2 Oxygen atoms.
Sugars and carbohydrates are combination of Carbon, Oxygen, Hydrogen
Proteins Carbon, Hydrogen, Oxygen and Nitrogen
A molecule can be as simple as 2Hydrogen atoms or as complicated as DNA

What does non polar molecule mean?
When a molecule is nonpolar it means there are no charges.
How might the size of a molecule affect the way in which an organism obtains the nutrients in that molecules?
The size of a molecule may affect the way in which an organism obtains the nutrients because the larger the molecule you have, the more the element can hold, so that would mean that there would be more nutrients for the organism.
A characteristic of a DNA molecule that is not a characteristic of a protein molecule is that the DNA molecule?
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
Is an oxygen molecule an organic molecule?
No, it's not organic (an organic molecule has to contain carbon.)
How Can I Compare new double-stranded DNA models with an original DNA Model?
Please elaborate. If you mean how to compare the replicated DNA molecule with the original, there is no point because the replicated DNA molecule is an EXACT copy of the original.
What does a molecule mean?
A diatomic molecule is a molecule made up of two atoms.
What does non polar molecule mean?
When a molecule is nonpolar it means there are no charges.
What two molecule types are needed to form a molecule or a fat?
You mean of a fat?
What is hydrolyze mean?
When you add a hydroxide group to a particular molecule by adding an H2O molecule
What is the antonym of molecule?
If you use molecule to mean 'tiny piece' then 'whole' would be the antonym.
What is the heat which travel molecule to molecule?
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
What does molecule of an element mean?
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.
Why is molecule polar?
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.
What does a negative Hf for molecule mean?
Energy was released when the molecule was formed from its elements
What molecule has a positive end and negative end?
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
What does the prefix gluc mean?
It usually shows that a molecule contains a grouping similar to the glucose molecule.
Why is there an extra hydrogen molecule in sucrose?
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".
