U1S1- Electronegativity Flashcards
1
Q
Electronegativity
A
The power of an atom to attract the pair of electrons in a covalent bond.
2
Q
Electron density
A
The probability of electrons being in a particular volume of space.
3
Q
Permanent dipole
A
It’s the uneven distribution of charge across a whole molecule.
4
Q
Instantaneous dipole
A
Electrons are constantly moving. If they are not evenly distributed one end of the molecule will have a greater negative charge than the other.
5
Q
Induced dipoles
A
A dipole may attract or repel electrons in an unpolarised molecule creating an induced dipole.
