Why does the oxygen atomhave more electrons surrounding it than a hydrogen atom?
A hydrogen only has one valence electron, while oxygen has 6.
What property of oxygen makes it share electrons unequally with hydrogen atoms?
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.
What causes the water molecule to have a negative charge?
The water molecule does not have a negative charge. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. This is because the oxygen atom is more electronegative than the hydrogen atoms, and tends to hold the shared electrons more tightly than the hydrogen atoms.
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).
What happens when shared electrons between hydrogen and oxygen spend more time orbiting the oxygen than the hydrogen and what effect does this have on water molecules?
If you think of it in terms of time, the electrons always spend more on the oxygen. This creates polar bonds, and as the molecule is not symmetrical, it means that the whole molecule is polar.
Does hydrogen have more electrons than Uraniu?
NO!!!! Hydrogen has only ONE(1) electron Uranium has NINETY TWO(92) electrons.
Does the chlorine atoms in hydrogen chloride have a stronger attraction for the electrons than the hydrogen atoms do?
Yes, the chlorine atom in hydrogen chloride has a stronger attraction for electrons compared to the hydrogen atom. This is because chlorine is more electronegative than hydrogen, meaning it has a greater tendency to attract electrons towards itself. This results in a polar covalent bond in which the electron pair is more strongly attracted to the chlorine atom.
The electrons in the bond between hydrogen and fluorine are more strongly attracted to which atom?
The electrons in the bond between hydrogen and fluorine are more strongly attracted to the fluorine atom. Fluorine has a higher electronegativity than hydrogen, meaning it has a stronger pull on the shared electrons in the bond.
Does hydrogen have more electron than uranium?
No, Uranium has far more electrons. In a neutral atom number of electrons=number of protons=atomic number. Hydrogen has 1 electron. Uranium has 92.
Does hydrogyen have more electrons than uranium?
No. Hydrogen has 1 electron. Uranium has 92.
Is hydrogen more electronegative than sulfur?
No, sulfur is more electronegative than hydrogen. Hydrogen has an electronegativity value of 2.20 on the Pauling scale, while sulfur has a value of 2.58. This means sulfur has a greater tendency to attract electrons in a chemical bond compared to hydrogen.
Which element in H20 is more electronegative?
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.
Does hydrogren pulls on the shared electrons more than oxygen in water?
No, the opposite occurs. As the oxygen atom is much larger, it has a bigger 'pull' on the shared electrons, creating an uneven distribution of electrons known as a permanent dipole. No, Oxygen pulls the electrons more strongly than the Hydrogen, resulting in a partial negative charge on the Oxygen, and partial positive charges on the hydrogens.
Why is the bond between hydrogen and oxygen in a water molecule is more polar than the bond between hydrogen and nitrogen in a ammonia molecule?
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).
Is hydrogen more electronegative than chlorine?
No, on the Arbitrary Pauling Scale hydrogen's relative electronegativity is less than that of chlorine, indicating that hydrogen attracts electrons in a bond more strongly. In hydrogen chloride (hydrochloric acid as an acid) the two shared electrons would be pulled towards hydrogen in a polar covalent bond. F, Cl, N, and O are the four most electronegative elements. Metals are least electronegative and nonmetals are the most.
Explain why in a covalent bond between oxygen and hydrogen the hydrogen atom has a partial positive charge and the oxygen atom has a partial negative charge?
Because, unless bonded to another hydrogen atom, the "covalent" bond is actually partially ionic, meaning the electron shared in the bond tends to spend more time close to the other atom making the hydrogen partially positive. This is due to electronegativity. Most other atoms are more electronegative than hydrogen, meaning they have a stronger attractive force for electrons than hydrogen does, so the other atom pulls on the hydrogen more strongly and ends up being more negative in the bonding pair than hydrogen.
Why does the oxygen atomhave more electrons surrounding it than a hydrogen atom?
A hydrogen only has one valence electron, while oxygen has 6.
