In a covalent bond, what do the two atoms do with electrons?
Table salt (sodium chloride) is held together by ionic bonds between positive and negative ions.
Why can metals conduct electricity?
Breaking a chemical bond releases energy.
Using Pauling electronegativities of 0.93 for sodium and 3.16 for chlorine, calculate the electronegativity difference for the Na–Cl pair (two decimal places).
How did Linus Pauling obtain his electronegativity values?
Solid sodium chloride does not conduct electricity, but molten or dissolved sodium chloride does. Explain why, using its bonding.
Using Pauling values, hydrogen fluoride has an electronegativity difference of 1.78 but is polar covalent, while manganese(II) iodide has 1.11 but is ionic. What does this tell you about using Δχ to classify bonds?
