Does the chlorine atoms in hydrogen chloride have a stronger attraction for the electrons than the hydrogen atoms do?
Yes. The electronegativity of chlorine is more than that of hydrogen. As such, the electrons are closer towards chlorine than hydrogen in HCl.
Why can't hydrogen have more than 2 electrons in its valence shell?
If it had more than two electrons it would no longer be hydrogen.
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).
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.
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.

The electrons in the bond between hydrogen and fluorine are more strongly attracted to which atom?
They are more strongly attracted to the fluorine. We say that fluorine is more electronegative than hydrogen.
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.

The chlorine atoms in hydrogen chloride have a stronger attraction for the electrons than the hydrogen atoms do The hydrogen chloride molecule is therefore a nonpolar covalent molecule?
True. A measure of the ability of an atom to "attract" electrons is electronegativity. Cl is more electronegative than H.

Why does the oxygen atomhave more electrons surrounding it than a hydrogen atom?
A hydrogen only has one valence electron, while oxygen has 6.
Why does the oxygen in a water molecule have a negative charge?
Oxygen attracts electrons more strongly than hydrogen does.

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 causes water to display such strong hydrogen bonding?
When you put hydrogen and oxygen together, the electrons spend most of their time on oxygen since it is more electronegative than hydrogen. This causes there to be a "partial charge" on both hydrogen and oxygen. Since oxygen has the electrons spending more time on it, it is more negative than hydrogen. So in H2O, the hydrogens are slightly more positive than the oxygens. When water molecules come near each other, the slightly positive hydrogens are then attracted to the slightly negative oxygens, and you end up having hydrogen bonding.
