Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom the molecule is nonpolar.?
That statement is incorrect. HF is a polar molecule because fluorine is more electronegative than hydrogen, causing the electron density to be pulled closer to the fluorine atom. As a result, HF has a partial positive charge on the hydrogen atom and a partial negative charge on the fluorine atom.
A hydrogen bond forms when a positively charged hydrogen ion bonds to a negatively charged atom?
No, hydrogen bonding occurs in covalent compounds in which hydrogen is bonded to nitrogen, oxygen, or fluorine. These elements will pull electrons towards them getting a partial negative charge and giving hydrogen a partial positive charge.The actual hydrogen bonding occurs when the partial positive charge on one such molecule is attracted to the partial negative charge on another.Technically it isn't a type of bond.
Why is water a polar molecule but fluorine is not?
In a molecule of water, you have a bunch of unshared electrons on the oxygen side of the molecule (the negative end) and no electrons and two hydrogen nuclei on the hydrogen end (the positive end.) This makes for very strong polarity, since a positive end and a negative end can be thought of as poles. Fluorine, on the other hand, is a diatomic element consisting of two fluorine atoms covalently bonded together. This means each of the two fluorine atoms contribute one electron to the bond. The remaining six from each atom are on the other side of the molecule from the bond. Six on one side and six on the other means no difference in charge across the length of the molecule, so there are no poles.

What can be a negative for electrons or a positive for protons?
The charge of electrons is negative and of protons is positive.
Does fluorine have negative or positive electrons?
All electrons are negatively charged.Fluorine forms a negatively charged ion.
Which is the appropriate representation of the H - F bond where fluorine is more electronegative than hydrogen?
A polar bond with a small negative charge on the fluorine and a small positive charge on the hydrogen

When potassium and fluorine bind what one will be the positive ion and which one will be the negative ion?
Potassium will be the the positive ion, and fluorine will be the negative ion because the potassium atom will give one electron to fluorine for they can both be stable. Fluorine will receive one electron from potassium and it will be stable because it has now 8 valence electrons. Giving is positive and receiving is negative. Hope this helps.
What happens when hydrogen's electron gets close to the valence shell of a fluorine atom?
When hydrogen and fluorine atoms bond, a permanent net dipole forms resulting from hydrogen being covalently bonded to the fluorine as hydrogen bonds form. the hydrogen bond is the strongest type of intermolecular force since the hydrogen nucleus is extremely small and positively charged and fluorine is very electronegative so that the electron on the hydrogen atom is strongly attracted to the fluorine. this leaves a highly localised positive charge on the hydrogen atom and highly negative localised charge on the fluorine. this means the electrostatic attraction between these molecules will be greater than for the polar molecules that do not have hydrogen covalently bonded to either fluorine. because the fluorine atom is unstable, as is the hydrogen, because they have not filled up their valence shell, they bond together quickly, and because of their opposing charges, very strongly. have a look at some online animations, with will become very clear to you. (-) (-) (-) (strong hydrogen bonds) (-) F ----------------------------------------… H (+) (-) (-) it looks a little bit like that, the (-) negative charges on the fluorine attract the positive (+) charge on the hydrogen, forming in hydrogen bonds (----). The fluorine has 7 electrons and the (---) is where both H and F share the electron.

Which atoms will form an ionic bond?
A positive ion and a negative ion. two oppositely charged ions
Does fluorine form an ion with a positive charge?
NO !!!! Fluorine form an ANION , that is an ion eith negative charge. 'F^(-) '.

The charge of electrons is negative and of protons is positive.
What parts of the atom have a positive charge?
Parts of an atom: - protons - located in the nucleus - have a positive charge - neutrons - located in the nucleus - have a neutral or no charge - electrons - are in orbit around the nucleus - have a negative charge
