What does it mean for a water molecule to be polar?
It means there is a positive side and a negative side to it. The 2 atoms of Hydrogen in a water molecule bond asymetrically to the oxygen atom. Like this O / \ H H Instead of this way H--O--H The molecule then has a more positive charge on the Hydrogen side of the molecule and a negative charge on the Oxygen side. ( When a molecule is polar, it means that the molecule has been given a charge. In water, H2O, Oxygen has a charge and so does hydrogen. However, because there is such a large difference in electronegativity between the Oxygen and the Hydrogens, then the distribution of electrons within the molecule becomes uneven. This causes one end of the molecule to contain a slightly postive charge and the other end to possess a slightly negavtive charge. ) Hope This WiLL HeLp u !! ))
What is the effect of this uneven sharing of electrons in water?
The polarity of water.
What makes the water molecule polar?
a water molecule is polar because their is an uneven distributive of electrons between the oxygen and hydrogen atoms. the negative pole is near the oxygen atom and the positive pole is between the hydrogen atoms.
In gram staining why will very thick smears give inaccurate results?
If a smear exhibits uneven thickness, overlapping cells may not get the proper exposure to the reagents. This results in uneven or mottled staining. For example, in the thicker areas of the smear, gram-negative cells may not decolorize sufficiently and end up staining purple.
What causes water to a polar molecule?
Because of its shape. it is a bend molecule. Since Oxygen is more electronegative that hydrogen, you get something called a net dipole making the oxygen "delta" negative. this makes the hydrogen delta positive since the oxygen atom is more electronegative ( i like to think of it as being "hungry for electrons" or a selfish atom that hogs the electrons), the electrons spend more time orbiting the oxygen that it does the hydrogens. therefore the oxygen is slightly (or delta) negative and the Hydrogen, since the electrons spend less time in orbit around the hydrogen, is delta (slightly )positive since an electron has a negative charge.
Molecules that have an unequal distribution of charges?
A molecule with an uneven distribution of charge is said to be a polar molecule. A polar molecule, because of an uneven distribution of charge, basically has an "end" that is slightly more positive and another that is slightly more negative. Let's look at an example.The water molecule is a good example of a polar molecule. It's oxygen end is a bit more negative, and the end with the pair of hydrogen atoms on it is slightly more positive. That gives the molecule an overall "endedness" with a positive and a negative end.
What is the definition of the root word ion?
an atom with a positive or negative charge caused by an uneven amount of electrons (even to the # of protons that is)
What is a molecule that has a negative charge on one side and a positive on the other?
If you're talking about formal charges, I think "zwitterion" is the word you're looking for. If that doesn't sound right, try "amphoteric" which technically isn't quite the same but is a related concept. If you mean partial charges, then "polar" or "dipole" are possibilities.
What are two non polar molecules?
An uneven distribution of charge
Atoms gain or lose electrons to form ions?
They can do both to form ions. An ion simply means that there is an uneven distribution of charge, so it can be positive or negative.
Does water have polar molecules?
Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge () near the oxygen atom due the unshared pairs of electrons, and partial positive charges () near the hydrogen atoms. An electrostatic attraction between the partial positive charge near the hydrogen atoms and the partial negative charge near the oxygen results in the formation of a hydrogen bond. The ability of ions and other molecules to dissolve in water is due to polarity. For example, sodium chloride in its crystalline form will dissolve in water.
An atom with an unbalanced electrical charge is called?
ion That statement isn't true. An ion is an atom with an uneven amount of protons and electrons.
What type of electrical charge is associated with a single atom?
If an atom has an even number of protons and electrons, it has no charge, so it is neutral. If it has an uneven number of protons or electrons and has a positive or negative charge depending on which has more. It is then called radioactive.
What is meant by polar and non-polar molecules?
Polar is when there's an uneven distribution of charge. So for water, H2O, there are two hydrogens and one oxygen. The oxygen is electronegative while the hydrogens are positive. So the electron density is higher around the oxygen making the oxygen side of the molecule negative and the hydrogen side positive. This is polar. Non polar is when the distribution of charge is pretty even; often fats and oils.
Why are water molecules polar?
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atomsAnswerA water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms. The negative pole is near the oxygen atom and the positive pole is between the hydrogen atoms.
Why is water cosidered to polar?
Water is considered to be a polar molecule because of its molecular structure. It is composed of two hydrogen atoms covalently bonded to a single oxygen atom which gives it a bent molecular geometry. This shape creates an uneven distribution of electrons leaving one side of the molecule slightly more negative than the other. This uneven charge distribution creates a dipole moment making it a polar molecule with partial positive and partial negative charges. The partial positive charge of the hydrogen atoms is attracted to the partial negative charge of the oxygen atom and vice versa. This creates a strong hydrogen bonding between the molecules making water a liquid at room temperature. These hydrogen bonds also create high surface tension in water allowing it to form droplets and hold its shape when held in the hand.
Do polar compounds have an uneven distribution of electrical charge?
Polar molecules have an even distribution of electrical charges. Water is made up of oxygen and hydrogen. Hydrogen (H) is made up of positive charges and Oxygen (O) is made up of one negative charge.
