Electronegativity Flashcards
1
Q
Electronegativity
A
a measure of the force of
an atom’s attraction for electrons it shares in a
chemical bond with another atom
– on Pauling’s scale, fluorine, the most
electronegative element, is assigned a
value of 4.0
2
Q
The attraction that a bonding pair of
electrons feels for a particular nucleus
depends on:
A
– the number of protons in the nucleus
– the distance from the nucleus
– the amount of screening by inner electrons
3
Q
No electronegativity difference between…
A
two atoms leads to a pure non-polar
covalent bond.
4
Q
A small electronegativity difference…
A
leads
to a polar covalent bond.
5
Q
A large electronegativity difference…
A
leads
to an ionic bond.
