1
Q
Define the term Electronegativity.
A
The ability of an atom to attract the shared pair of electrons towards itself within a covalent bond.
2
Q
State the 3 factors affecting electronegativity.
A
Nuclear Charge
Atomic Radius
Shielding
3
Q
Describe how and why nuclear charge affects electronegativity.
A
The negative electrons in the bond pair, are attracted to positive nuclei; so the more protons are found within the nucleus, the stronger the electrostatic force of attraction between the nucleus and shared electrons.
4
Q
Describe how and why atomic radius affects electronegativity.
A
Atomic Radius
