Electronegativity Flashcards
1
Q
Electronegativity
A
Measure of tendency of an atom to attracts a bonding pair or e- of a covalent bond.
/ how closely an atom tends to hog the e- in a bond,
The greater the EN, the more it attracts e-.
sort of like a spectrum:
covalent ———– ionic (-> increased EN diff.)
2
Q
Affected by:
A
Atomic charge
Distance from nucleous
Electron shielding
3
Q
Permanent Dipole
A
Every atom of 2 atoms have the different charges => polar covalent bonds => non-symmetrical molecule => a polar molecule
4
Q
Polar molecule
A
a molecule that is differently charged in different regions => polar covalent bonds
5
Q
Polar covalent bond
A
A bond between atoms where the e- are not shared equally (spend more time at one atom)
