Why is the structure of a water molecule polar?
Since oxygen is more electronegative than hydrogen, you get something called a "dipole moment," making the oxygen slightly negative because of the unequal sharing of electrons. This makes the hydrogen slightly positive since the oxygen atom is more electronegative (I like to think of it as being "hungry for electrons"); the electrons spend more time orbiting the oxygen than they do 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. O-H bonds are polar because O and H have different electronegativity values. The vector sum of the two bond dipoles is nonzero. (That is, they are not pointing in exact opposite directions.)

In the covalent bond between hydrogen and chlorine in the HCl molecule where will the majority of shared electrons be found?
They will be found around/near the Cl because Cl is more electronegative than H.
What is polarity and how does water use it?
Polarity is when one end of a molecule is slightly positive, and the other end is slightly negative due to unequal sharing of electrons. In a molecule of water, the electrons from the hydrogen ions travel around the oxygen atom because it is bigger, and so spend less time with the hydrogen atoms making that end slightly positive, and the other end slightly negative. Water uses its polarity to separate and surround ions in a molecule, breaking them apart and creating a solution. Water is a remarkably good solvent because of its polarity.
Is h20 an atom containing 2 hydrogen molecules and 1 oxygen molecule?
No, a H2O molecule, contains 2 hydrogen atoms and one oxygen atom - not the other way around as in the question.
When the electrons are revolving around Cl in HCl acid What is the name of H molecule?
The name of Hydrogen molecule is partial positive.
Is it true that in a water molecule the electrons within the molecule are attracted more towards the hydrogen atoms?
Water is a polar molecule where the electrons spend more time in orbitals around the oxygen atom because it is significantly more electronegative than the hydrogen atoms. So, false is the answer.
Why dont hydrogen and oxygen atoms share electrons equally in a water molecule?
Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
How many unshared pairs of electrons are in hydrogen iodide?
Oxygen has six (6) valence electrons. In the formation of a water molecule, two (2) of the valence electrons forms a covalent bond with two other hydrogen atoms leaving the water molecule with 2 unshared pairs of electron.
What are the partial charges in a water molecule?
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.

Where is the density of electrons greatest in the water molecule?
The density of electrons in a water molecule is highest around/near the oxygen atom.
How many nonbounding electrons are in the water molecule?
H-:O:-H Two lone pair around the oxygen. ( not drawn to Lewis dot structure standards )
What causes polarity in water molecule?
When a highly electronegative atom is attached to a less electronegative atom, then the former one attracts the shared pair of electrons towards itself. Such a molecule is polar molecule. Polarity of molecule means the product of charge on molecule and the distance between the atoms.
Is iodopropynyl butylcarbamate inorganic?
No, iodopropynyl butylcarbamate is classified as an organic molecule due to the prevalence of carbon and hydrogen atoms within the molecule. Although there are other atoms, notably iodine, in the structure, the backbone is made of carbon atoms with multiple hydrogen atoms around the carbon backbone.
What does a Lewis dot structure do?
A Lewis dot structure tells chemists a great deal about the structure and bonding in a molecule. It is used to understand what types of bonds exist in the molecule (whether there are single, double or triple bonds, for instance). It can also be used to determine how molecules will react and what some of their properties will be. It can also be used to determine the shape of a molecule and the position of each of the atoms in the molecule (to do this you must also use something called VSEPR, or valence shell electron repulsion theory along with the Lewis dot structure).See the Related Questions to the left for how to draw a Lewis dot structure of any molecule.
What caused polarity in a water molecule?
The oxygen atom is much more electronegative than the hydrogen atoms, meaning that it draws the electrons toward it more than the hydrogen atoms do. this causes a dipole moment, meaning that the molecule, even though it is neutral overall, has areas where there is a greater electron density than other areas of the molecule. the shared electrons spend a disproportionately high amount of time around the oxygen atom than they do around the hydrogen atoms, making the oxygen a negatively charged region and the hydrogens a positively charged region.
