1.the properties of both ionic and covalent compounds are related to the
•ability of the electrons to move between atoms
•hydrogen bonding between atoms
•strength of attraction between the particles in the compound
•dispersion forces
2. the type of bond in a diatomic molecule of oxygen, o2 is
•polar
•nonpolar covalent
•hybridized
•nonpolar ionic
3. a molecule of hf is polar because
•it is ionic and all ionic bonds are polar
•hydrogen and fluorine are both ions
•hydrogen is a metal so exhibits magnetic properties
•the fluorine atom is able to attract the shared electrons more strongly than a hydrogen atom
true or false:
compared to covalent and ionic bonds, the strength of intermolecular forces are much weaker
4. the element symbols that make up the compound sodium citrate, which is used to make cheese melt faster, spell out this yummy 5 letter word. what is it?
