What Is a Hydrogen Bond? Hydrogen bonds are not “true” bonds like covalent and ionic bonds, but rather directional electrostatic attractions between slightly negative and slightly positive atoms. The standard configuration of a hydrogen bond is of the type D— H···A where: H is a hydrogen...
What is the basis of a metallic bond? Why are covalent bonds directional while ionic bonds are not? What is the reason that ionic compounds are brittle? What is the difference between ionic covalent and metallic bonds? How do metals and nonmetals bond?
Why are covalent bonds directional while ionic bonds are not? Why are covalent bonds between hydrogen and nitrogen or oxygen polar? Both CO2 and SiO2 exhibit covalent bonding, so why is CO2 not a covalent-network solid? If a covalent bond only occurs within a molecule, then why does it occ...
The melting point of methane is low, so why is that in terms of intermolecular forces? Is a hydrogen bond stronger than a covalent bond? How are hydrogen bonds and cohesion connected? Why do atoms form covalent bonds versus ionic bonds? Which intermolecular forces does a polar molecule h...
Are polar or non-polar bonds stronger? What is a polar covalent bond? How do a pure covalent bond, a polar covalent bond, and an ionic bond differ? In a polar covalent bond, why does the spare electron move closer to one nucleus over the other? Why are covalent bonds...
How is water a molecule and a compound? Why are covalent bonds directional while ionic bonds are not? What type of bond joins two hydrogen atoms? How does hydrogen bonding affect the boiling point of water? Does H2O have delocalized ...
What effect has a directional bond on the weight to volume ratio of in an atomic arrangement? Why do you think metals usually have higher densities than other materials? Why is the term molecular mass inappropriate for NaCl? Why is conservation of mass important to know for chemistry? Why...
