1 Bonding - IMF Flashcards
1
Q
Electronegativity meaning
A
Ability to attract the bonding pair of electrons towards itself in a covalent bond.
2
Q
What is the trend in electronegativity?
A
- Increases across a period as the nuclear charge increases and the electron sheilding remains the same
- Decreases down a group
3
Q
Factors affecting electronegativity
A
- Atom’s nuclear charge
- Atomic radius, diatnce betweeen nucleus and valent e-
- Sheilding of nuclear charge from e- in inner shells
4
Q
What is polarity?
A
Unequal polarity = unequal sharing of electrons in a covalent bond, if the electron sharing is equal =, the bond is non-polar
5
Q
What are the most electronegative atoms?
A
Fluorine
Oxygen
Nitrogen
6
Q
Permenant dipole
A
- Molecule containing atoms that have differing
