Polarity + Electronegativity Flashcards
1
Q
Electronegativity
A
The ability of an atom to attract the shared pair of electrons (electron density) in a covalent bond towards itself
2
Q
Factors that affect Electronegativity
A
- nuclear charge
- atomic radius
- shielding
3
Q
Electronegativity trend across a group:
A
- increases across a group
4
Q
Electronegativity down a period
A
- Decreases down a period
5
Q
What properties cause a dipole bond to form
A
The electronegativities of the elements are different
6
Q
What bond occurs when there is no dipole?
A
pure covalent
7
Q
what bond occurs when there is a dipole?
A
polar covalent
