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.
What else can I help you with?
How many electrons does a water molecule have?
A molecule of of H2O has 10 electrons: two from the hydrogen and 8 from the oxygen.
Hydrogen and oxygen are what type of bonds?
Polar Covalent Bond. This is when a pair of electrons is shared between two atoms in a molecule but the electrons are not equally shared. Because the Oxygen atom has a stronger pull on the electrons than the Hydrogen, the electrons will be more drawn to the Oxygen atom.
How many pairs of valence electrons are there on the oxygen atom in the water molecule?
There are 4 valence electrons on the oxygen atom in the water molecule. Oxygen has 6 valence electrons, and in a water molecule, oxygen forms 2 covalent bonds with the hydrogen atoms, sharing 2 of its valence electrons with each hydrogen atom.
How many electrons are in the outermost energy level of an oxygen atom as shares electrons with hydrogen atoms as part of a water molecule?
Eight. Oxygen has 6 electrons and shares two more with the hydrogen atoms in covalent bonds
If electrons in water molecules were equally attracted to hydrogen nuclei as well as oxygen nuclei water molecules would be?
If electrons in water molecules were equally attracted to hydrogen as well as oxygen nuclei, the molecule would be nonpolar. This means the charges would be evenly distributed throughout the molecule, causing it to have no overall charge.
What kind of charge is found on the oxygen atom of polar water molecule?
In a water molecule, the oxygen atom shares electrons with two hydrogen atoms, but it does not share equally since it has a stronger attraction for electrons than the hydrogen atom does, and the electrons therefore have a greater probability of being close to the oxygen nucleus than to the hydrogen nuclei. As a result, the oxygen atom has a negative charge. The hydrogen atoms are positively charged.
What type of bonds are oxygen and oxygen?
Polar Covalent Bond. This is when a pair of electrons is shared between two atoms in a molecule but the electrons are not equally shared. Because the Oxygen atom has a stronger pull on the electrons than the Hydrogen, the electrons will be more drawn to the Oxygen atom.
How many electrons does a water molecule have?
A molecule of of H2O has 10 electrons: two from the hydrogen and 8 from the oxygen.
Does a water molecule have more protons than electrons?
No, a water molecule contains the same number of protons and electrons. In a water molecule (H2O), there are 10 protons (2 from each hydrogen and 8 from oxygen) and 10 electrons (2 from each hydrogen and 8 from oxygen).
Hydrogen and oxygen are what type of bonds?
Polar Covalent Bond. This is when a pair of electrons is shared between two atoms in a molecule but the electrons are not equally shared. Because the Oxygen atom has a stronger pull on the electrons than the Hydrogen, the electrons will be more drawn to the Oxygen atom.
What is the bond between the hydrogen atoms of hydrogen gas in which electrons are shared equally?
In a water molecule, oxygen (which is a quite more electronegative than hydrogen), tends to attract electrons close to it, so it gets a residual negative charge, while hydrogen gets positively charged.That's the reason why water has a high boiling temperature, because water molecules establish electrostatic bonds, between the oxygen and hydrogen from different molecules, creating a kind of net of interactions, which make it harder to evaporate it.
How many pairs of valence electrons are there on the oxygen atom in the water molecule?
There are 4 valence electrons on the oxygen atom in the water molecule. Oxygen has 6 valence electrons, and in a water molecule, oxygen forms 2 covalent bonds with the hydrogen atoms, sharing 2 of its valence electrons with each hydrogen atom.
How many electrons are in the outermost energy level of an oxygen atom as shares electrons with hydrogen atoms as part of a water molecule?
Eight. Oxygen has 6 electrons and shares two more with the hydrogen atoms in covalent bonds
What is polarity in a water molecule?
Water molecule is a polar molecule because it has a slightly negative charge on the oxygen atom and slightly positive charges on the hydrogen atoms. This unequal distribution of charge creates a positive and negative pole in the molecule, making it polar.
If electrons in water molecules were equally attracted to hydrogen nuclei as well as oxygen nuclei water molecules would be?
If electrons in water molecules were equally attracted to hydrogen as well as oxygen nuclei, the molecule would be nonpolar. This means the charges would be evenly distributed throughout the molecule, causing it to have no overall charge.
Where would you most likely find shared electrons in a water molecule?
Shared electrons in a water molecule are most likely found in the covalent bonds between the oxygen and hydrogen atoms. In water, the oxygen atom shares electrons with the hydrogen atoms to form two polar covalent bonds.
Which kind of electrical charge is found on oxygen atom of a polar water molecule?
A negative charge that exists because of a covalent bond with hydrogen
