Bonding Flashcards
Summary
1
Q
Define Electronegativity
A
An atoms ability to attract a bonding pair of electrons in a covalent bond
2
Q
Define dipole
A
A difference in charge between 2 atoms caused by a shift in electron density in a covalent bond
3
Q
Hydrogen bonding features
A
1) hydrogen covalently bonded to fluorine, oxygen or nitrogen
2) these atoms very electronegative
3) bond is very polarised
4) hydrogen weakly attracted to negatively charged fluorine, nitrogen or oxygen on other molecules
4
Q
Define Metallic bonding
A
Many Strong electrostatic forces of attraction between positively charged ions and negative electron charge cloud
5
Q
