The Oxygen molecule and Hydrogen molecules have different electronegativity (due to position on Periodic Table). As Oxygen is more electronegative it draws the negatively charged electrons towards itself. This makes the hydrogen atoms more positive and hence the partial charges.

What is positively and negatively charged in a water molecule?
it says oxygen acts negativw so most likely hydrogen on the bottom acts positive
What is the oxygen atom of a water molecule?
Oxygen atoms in water molecules are the same as oxygen atoms in any other molecules; the definition of an oxygen atom is that it is an atom which has eight protons in its nucleus. Normally it has eight neutrons and eight electrons as well, but that can vary. It is only the eight protons which define it as oxygen.
Molecules that do not have oppositely charged ends are what molecules?
Molecules that do not have oppositely charged ends are nonpolar molecules.
Is a water molecule larger than a oil molecule?
no
Why oil does not dissolve in water?
Water dissolves substances because it's hydrogen bonds make it a polar molecule. Thus, the positive and negative ends of the water molecules attract the negative and positive ends (respectively) of substances, thus pulling them apart and dissolving the substance. Oil, however, is a nonpolar substance, so it is not attracted to the polarity of water.
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.
Why are polar covalently bonded molecules soluble in water and non polar are not?
Water is a polar covalent molecule. The partial charges in the molecule attract other charges, ionic or more partial charges from other covalent molecules and dissolves them. Nonpolar bonded molecules have no partial charges and the water molecules will attract each other thus not attracting the nonpolar and does not dissolve them.
Characteristics for polar and nonpolar molecues?
Polar molecules have separation of charges .ie. they have a partial positive and partial negative charges on molecule as in water . Non polar molecules e.g.methane has no separation of positive and negative charges as difference of electronegativity in C and H is very small .
What is a molecule that has a partial positive charge on one end and a partial negative charge on the other?
A polar molecule...such as water. The oxygen molecules pulls the electrons closer, causing the oxygen to have a more negative charge and the two hydrogen atoms to have more positive charges. this is very important in the bonding of water molecules to other water molecules.
What is polar in chemestry?
An atom or a molecule which has charge or a bond where the two atoms have partial charges.
How can be partial charges be shown in a polar covalent molecule?
Usually in electron-dot diagrams, partical charges are shown by the lower case delta
What is positively and negatively charged in a water molecule?
it says oxygen acts negativw so most likely hydrogen on the bottom acts positive
What is the overall charges on water molecule?
Neutral.
What charges does a polar molecule have on opposite ends?
A polar molecule doesn't necessarily have any overall charge. All polar means is that one part of the molecule has a negative charge and another part of the same molecule has a positive charge. These charges balance. When the charges don't balance and there is a net charge, it is referred to as an ion. An example of a polar molecule is fluoro-methane, or CH3F. The fluorine attracts the electrons in the bond a lot harder than carbon. so the fluorine has a negative charge while the carbon atom ends up with a positive charge.
Give one reason why water molecules are attracted o each other?
The H atoms with partial + charges attract O atoms with partial - charges on other water molecules.
What are the bonds between atoms that make up water molecules?
Those are covalent bonds.Bonds between water molecules are defined as polar covalent where there is an unequal distribution of partial charges.
Why is a water molecule considered to be a polar molecule?
A water molecule is considered a polar molecule because of its shape. That is, its poles contain opposing charges, the positive and negative charge.
