Bonds Flashcards
happens when a positive ion (cation) and a negative ion (anion) attract each other
ionic bond
atoms share pairs of electrons to fulfill octet rule
covalent bond
covalent bond with high electronegativity difference between the two atoms
polar covalent bond
covalent bond with low electronegativity difference between the two atoms
nonpolar covalent bond
delocalized electrons in geometrical arrangement of the two metals
metallic bond
h-atom bonded to highly electronegative atom is simultaneously attracted to a highly electronegative atom of another molecule
hydrogen bonding
an induced dipole created in a nonpolar molecule which allows it to attract different molecules
london dispersion forces
ions and polar molecules tend to align each other due to having positive and negative sides
ion-dipole interactions
polar molecules tend to align with each other due to having positive and negative sides
dipole-dipole interactions
strengths of intermolecular forces
