Electronegativity Trends And Chemical Bonding
Which of the following statements about electronegativity is true?
A
Noble gases are generally excluded from standard electronegativity trends.
B
Electronegativity generally increases from left to right across a period and from bottom to top within a group, excluding most transition metals and noble gases.
C
A slight difference in electronegativity between two atoms results in the formation of a polar covalent bond.
D
When the electronegativity values of two atoms are approximately equal, a nonpolar covalent bond forms.
E
All of these statements are true.
