15 Questions
What is electronegativity defined as?
The ability to pull electrons from another atom and hold them tightly
On Linus Pauling's electronegativity scale, which element is the most electronegative?
Fluorine
What property of an element does a high electronegativity value predict?
Efficient attraction and holding of electrons
Which element has an electronegativity value close to 0 according to Pauling's scale?
Francium
What type of bonds are formed when electrons are shared between atoms?
Covalent bonds
Which statement accurately describes a nonpolar covalent bond?
Electrons are shared equally between two atoms.
What electronegativity difference value indicates a nonpolar covalent bond?
Less than 0.5
How does the number of protons in an atom affect electronegativity?
Increasing the number of protons increases electronegativity.
Which type of bond has a polar covalent nature?
N-H
What is the significance of the electronegativity trend across a period?
Electronegativity values increase across a period.
Why does electronegativity decrease down a group in the periodic table?
Because moving down a group results in a gain of electrons that are farther away from the nucleus.
How does the number of electron shells between the nucleus and the outermost electron affect nuclear shielding?
More electron shells increase nuclear shielding.
Why do noble gases have electronegativity values of 0.0 in the periodic table?
Because they have full outer shells and do not need to share electrons.
Why do nonpolar and polar substances not mix?
Due to the difference in their electronegativities.
Why are drugs with N-H or O-H bonds very soluble?
Due to their high polarity because of electronegativity differences.
