Why does the oxidation number change for elements with multiple oxidation states and what happens to those electrons? Do nonmetals gain or lose electrons? Why do metals and nonmetals form ionic compounds? Why are the halogens among the most reactive nonmetal elements? Why is an atom electrically...
Alcohols have higher boiling points than parent hydrocarbons because of View Solution Assertion: Boiling point of pentane is higher than 2,2-dimethylpropane. Reason: There is steady increase in boiling point with increase in molecular mass.
In this lesson, we first review the meaning of valence and covalence for the elements. We then describe how some elements can have multiple different valences and covalences. In other words, some elements do not always form the same number of bonds or have the same charge (if they form i...
