Polarity Flashcards
1
Q
purely covalent
A
forms between two identical atoms, electrons are shared equally
2
Q
polar covalent
A
two different atoms, electrons are not shared equally, the electron pair spends more time near the nucleus of the more electronegative atom.
3
Q
what do polar covalent bonds have
A
the polar covalent bonds between atoms of differing electronegativity have a bond dipole.
4
Q
what is the net dipole
A
overall movement of the electrons.
5
Q
polar molecules
A
have an uneven charge distribution (overall net dipole)
6
Q
non polar molecules
A
have an even distribution of charge through (net dipole of zero)
7
Q
net dipole in symmetrical and non symmetrical molecule
A
symmetrical - net dipole of zero
non symmetrical - net dipole is not zero.
8
Q
