H-F

Explanation:

Hello,

To state which is the most polar bond we must perform the subtraction between the hydrogen's electronegativity and the other atoms' electronegativities, nevertheless, since the fluorine is the most electronegative element, such difference is the greatest one, therefore, the H-F has the most polar bond (in fact, it reaches the ionic bond). Lets substantiate it via the calculations:

Best regards.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
