electronegativity Flashcards
1
Q
what is electronegativity?
A
the measure of the tendency of an atom to attract a pair of electrons
2
Q
what is bond polarity?
A
3
Q
What is the highest and lowest electronegative elements?
A
Flourine - highest
Francis - lowest
4
Q
Electronegativity across a period?
A
the EN increases across a period as the nucleus charge increases
5
Q
Electronegativity down a group?
A
the EN decreases down a group as atomic radius increases
6
Q
what happens in a non-polar bond?
A
the electron pairs are shared equally as the atoms are the same, or the atoms have very similar EN
7
Q
what happens in a polar bond?
A
the electron pairs are shared unequally as there is a difference in electronegativity
