Different elements have different electro-negativities. Electro-negativity is the ability of an atom to withdraw 'electron density' towards itself, i.e. it makes electrons come closer to it.
Fluorine is the most electronegative of the elements.
Oxygen is more electronegative than hydrogen and so in water (H2O) the oxygen 'pulls' the electrons closer to itself and become slightly negative, and the hydrogen's slightly positive, this is called a permanent dipole.
Due to this effect water has many properties that make it unusual and important to living things.
What else can I help you with?
Is a polar molecule is a molecule with the ability to resists changes in temperature?
A polar molecule is a molecule with slight opposite charges. Water is a polar molecule which means that each water molecule is attracted to other water molecules which accounts for waters surface tension or cohesion.
Is water ionic?
Water is a polar molecule, not ionic.
What is a H20 polar molecule?
A H2O polar molecule is a molecule of water where the oxygen atom is more electronegative than the hydrogen atoms, leading to an uneven distribution of charge within the molecule. This causes water to have a partial negative charge at the oxygen atom and partial positive charges at the hydrogen atoms, making it a polar molecule.
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.
Is red 40 polar or nonpolar?
Red 40 is a polar molecule due to the presence of polar bonds between carbon and oxygen atoms. This makes the molecule soluble in water.
What happens if water is a polar molecule?
Water IS a polar molecule.
Could Water be a polar molecule?
Water is a polar molecule.
Is H2O a Polar molecule?
H2O is a water molecule, which is polar.
What does the composition of a water affect its charge?
It makes the molecule polar
Is Hsub2O a polar molecule or nonpolar?
I will assume Hsub2O is H2O [water] Water is a polar molecule.
Is tap water polar or non polar?
Water is polar molecule. Since oxygen has a higher electronegativity than hydrogen.
Is h2o molecule polar or nonpolar?
It is polar because it is asymmetrical
Is water a polar or nonpolar molecule?
Water is a polar molecule because it has a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms due to differences in electronegativity. This unequal sharing of electrons gives water a polarity, making it a polar molecule.
Why does water and oil separate?
water is a polar molecule. so it doesn't attract to oil (another polar molecule)
Why toluene is insoluble to water?
Toluene is an aromatic hydrocarbon and like all hydrocarbons is a non polar molecule. Water is a polar molecule. The rule of dissolving is that non polar cannot dissolve in polar
Is water composed of polar bonds?
Yes, water has polar bonds, and is a very polar molecule.
Water is polar or non polar?
Water is polar molecule since oxygen has a higher electronegativity than hydrogen.
