because oxygen needs 2 electron to complete it's valance shell. Whereas hydrogen does not want to complete it's valance shell, it wants to lose its electron.
A carbon-oxygen bond is more polar than a carbon-hydrogen bond, because the difference in electronegativity between carbon and oxygen is greater than the difference in electronegativity between carbon and hydrogen.
Oxygen has a higher electronegativity than nitrogen does, so when sharing electrons with hydrogen, the sharing is more uneven in the case of oxygen than it is with nitrogen. Oxygen, in other words, will attract electrons more strongly than nitrogen does and therefore will wind up with a more negative charge (hydrogen, which supplies the extra electrons to the oxygen, has a correspondingly higher positive charge).
No, oxygen is more electronegative than calcium. Oxygen has a higher electronegativity value on the Pauling scale compared to calcium, indicating it has a stronger tendency to attract electrons in a chemical bond.
The bond between oxygen and hydrogen would be classified as a polar covalent bond due to the difference in electronegativity between the two atoms. Oxygen is more electronegative than hydrogen, leading to an uneven sharing of electrons in the bond.
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.
A carbon-oxygen bond is more polar than a carbon-hydrogen bond, because the difference in electronegativity between carbon and oxygen is greater than the difference in electronegativity between carbon and hydrogen.
Hydrogen's electronegativity is only about 2.1 while oxygen has 3.0, so no.
The high electronegativity of oxygen makes it attract electrons more strongly than hydrogen. This unequal sharing of electrons creates a polar covalent bond due to the partial negative charge on oxygen and partial positive charge on hydrogen.
Oxygen is more electronegative than hydrogen in H2O. Oxygen has a stronger pull on electrons due to its higher electronegativity, causing it to attract the shared electrons more strongly in the water molecule.
No, calcium has a higher electronegativity than magnesium. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond, and calcium (Ca) has a higher electronegativity value than magnesium (Mg) on the periodic table.
Oxygen has a higher electronegativity than nitrogen does, so when sharing electrons with hydrogen, the sharing is more uneven in the case of oxygen than it is with nitrogen. Oxygen, in other words, will attract electrons more strongly than nitrogen does and therefore will wind up with a more negative charge (hydrogen, which supplies the extra electrons to the oxygen, has a correspondingly higher positive charge).

The bond between oxygen and hydrogen would be classified as a polar covalent bond due to the difference in electronegativity between the two atoms. Oxygen is more electronegative than hydrogen, leading to an uneven sharing of electrons in the bond.
H2O (water) is more polar than H2S (hydrogen sulfide) because oxygen is more electronegative than sulfur. This results in a greater difference in electronegativity between the hydrogen and oxygen atoms in water, leading to a more polar 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.
H2O is more polar than H2S because oxygen is more electronegative than sulfur, resulting in a greater difference in electronegativity between the hydrogen and oxygen atoms in H2O compared to H2S. This difference creates a stronger dipole moment in H2O, making it more polar overall.
Water is polar molecule since oxygen has a higher electronegativity than hydrogen.
