Bond Types
What is the type of bond formed when valence electrons are shared
Covalent
What is the intermolecular force created between molecules with oppositely charged ends?
dipole
What is the charge on an ion when the atom loses 2 electrons?
2+
What is the bond formed when valence electrons are transferred
Ionic
What is force of attraction between unpaired electrons of a highly electronegative element of one molecule and a hydrogen atom of another molecule?
hydrogen bond
What is the charge on an ion when the atom gains two electrons
2-
What is the reason for higher melting/boiling points?
Greater intermolecular forces
What is the type of bond formed when electrons are free and loosely shared?
metallic
What is the intermolecular force involved when molecules can't form H-bonds or dipole interactions
dispersion force
What compounds have the highest melting/boiling points
Ionic Compounds
What is the bond formed between a metal and a nonmetal?
ionic
What is the relationship between intermolecular forces and melting/boiling point?
The stronger the intermolecular forces, the higher melting/boiling point
What intermolecular forces are responsible for the lowest boiling points
dispersion forces
What is bond formed when two nonmetals bond together?
covalent
What is the strongest of the intermolecular forces?
hydrogen bonds
Between hydrogen bonds and dipole interactions, these will have lower boiling points.
What is dipole interactions?
