Contrast two general types of chemical bonds in terms of the mechanism by which they form?
|
Ionic Compounds and Molecular Compounds. differ on the basis of general PHYSICAL PROPERTIES:Ionic compounds have higher melting points and are good conductors of electricity when they are in a (liquid state) or in solution.Molecular Compounds lower melting point and tend to be gases, liquids, or low melting-point solids.they do not conduct electricity in the molten state.

Answer |
|
What is the chemical property of the noble gases that leads to the conclusion that they possess extremely stable electron arrangements?
|
They are the most stable due to having the maximum number of valence electrons their outer shell can hold.Therefore, they rarely react with other elements since they are already stable.
