What are ions and polar molecules termed?
Ions and polar molecules are collectively referred to as "polar species" because they possess an uneven distribution of charge due to the presence of partial or full charges within the molecule.
What does hydrophilic heads mean?
Polar molecules are those which have a permanent electric dipole moment. What this means is that although the molecule may have an overall neutral charge, one part of it is more negative than the other.Using water for example, the oxygen is more electronegative and so this end of the molecule is more negatively charged.ANSWER:*to assist with understanding, open this link in another browser for diagrammatic reference.http://kvhs.nbed.nb.ca/gallant/biology/p…If you think of the hydrogen bonding in water it become clear why polar molecule are water-loving (or hydrophilic). The polarity this has gives the molecule a partial charge for the molecule allowing it to hydrogen bond with water.Contrastingly, hydrophobic molecules are non-polar; that is, there is no partial negative or positive charge anywhere on the molecule. Because of this, it repels water.So in short, those molecule which are polar and have a dipole moment will be hydrophilic and those molecules with no dipole moment (non-polar) are hydrophobic.Relating this to phospholipids and plasma membranes, the phospholipid can be divided into two sections to examine. The "head" part of the molecule is polar (having a partial charge due to electronegativity) and therefore does not resist interaction with water.Because of this, the heads of one layer will be in contact with the outside of the cell and the heads of the other layer in contact with the cytoplasm of the cell.The hydrophobic tails avoid the water and arrange themselves in the middle of the 2 layers.HYDROPHOBIC = NON-POLAR
What struggle produces the partial negative and partial positive charges on a water molecule?
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
What is in a substance that makes it hydrophobic?
Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges. Water is a polar molecule so it tends to be attracted to other molecules that are polar as well. This is often summed up as "like attracts like". Some examples of hydrophobic molecules include fats and oils which are nonpolar because they have large hydrophobic hydrocarbon chains.
Is NOCl dipole?
Yes, NOCl (nitrosyl chloride) is a polar molecule and has a dipole moment. This is due to the difference in electronegativity between nitrogen and chlorine, which results in an uneven distribution of electron density. The nitrogen atom carries a partial positive charge while the chlorine atom carries a partial negative charge, creating a dipole. Additionally, the molecular geometry contributes to its polarity.

Is N-H hydrophobic or hydrophilic?
N-H bonds are typically considered hydrophilic due to the electronegativity difference between nitrogen and hydrogen, leading to partial charges on the atoms and the ability to form hydrogen bonds with water molecules.

What is a molecule that has a partial positive charge on one end a partial negative charge on the other?
This is a polar molecule.
What struggle produces the partial negative and partial positive charges on a water molecule?
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
Which line of electrical charge is found on the oxygen atom of a polar water molecule?
The oxygen atom in a polar water molecule carries a partial negative charge. This is because oxygen is more electronegative than hydrogen, pulling the shared electrons closer to itself and creating a partial negative charge on the oxygen atom.
What type of charge does a hydrogen atom of an ammonia molecule have?
A hydrogen atom of an ammonia molecule has a slight positive charge, due to the high electronegativity of the nitrogen atom.

Can A Particle Be A Molecule Yes Or No?
yes, a partial can be a molecule. In fact, It can be anything!
A polar molecule has a partial positive side and partial negative side true or false?
True. A polar molecule has regions of positive and negative charge due to an uneven distribution of electrons, leading to a separation of charges within the molecule. This creates a partial positive side and a partial negative side.
Is a phosphate head hydrophilic?
Yes, it is. The phosphate group is polar, and is attracted to water, which is also polar. Hydrophilic = attracted to water. The oxygens are very electronegative and carry a partial negative charge. This is attracted to the partial positive hydrogens of water, forming hydrogen bonds.
