To figure out if a bond between two atoms is polar, or how "charged" it can be, you can follow these simple steps:

1. Identify the Atoms: Start by looking at the two elements that are making the bond.

2. Check Electronegativity: Next, find their electronegativity values using the periodic table. Electronegativity shows how much an atom wants to attract electrons.

3. Calculate the Difference: Subtract the smaller electronegativity value from the larger one. You can do this like this: $\text{Difference} = |\text{EN}_1 - \text{EN}_2|$

4. Determine Polarity: Now, look at the difference you calculated:

   • If the difference is greater than 1.7: It’s an ionic bond.
   • If the difference is between 0.4 and 1.7: It’s a polar covalent bond.
   • If the difference is less than 0.4: It’s a nonpolar covalent bond.

These steps make it easy to understand how charged a bond can be!
