15 Questions
What is the definition of electronegativity?
The ability to pull electrons from another atom and hold them tightly
Which element has the least electronegative value on Pauling's scale?
Francium
How does the electronegativity value of an element affect its ability to attract or hold electrons?
Higher electronegativity means higher ability to attract or hold electrons
Which type of bonding involves the sharing of electrons between atoms?
Covalent bonding
What is the most electronegative element according to Linus Pauling's scale?
Fluorine
What determines if a covalent bond is polar or nonpolar?
The electronegativity difference
What does an electronegativity difference (ΔEN) of 0 indicate about a covalent bond?
It is nonpolar
According to the electronegativity values in the text, which bond is classified as polar covalent?
C-O
Why do nonmetals on the right side of the periodic table have higher electronegativities?
Due to having stronger nuclear charge
How can the trend of increasing electronegativity across a period be explained?
By considering the number of protons in the atom
Why does electronegativity decrease down a group on the periodic table?
As electrons gain energy shells farther from the nucleus, there is increased nuclear shielding.
Why do most noble gases have an electronegativity value of 0.0?
They have full outer shells of electrons and do not need to share or transfer electrons.
Why do elements with atomic numbers above 104 have electronegativity values of 0.0?
They have radioactive nuclei that break down, preventing accurate measurements.
What makes long chain fatty acids found in oils and fats nonpolar?
Equal electronegativities of carbon and hydrogen atoms
How is the polarity of the amide bond used in drug manufacture?
To enhance solubility and effectiveness of drugs
