Final answer:
The mixing of lithium (Li) with sodium fluoride (NaF) will result in no reaction, as elements in the same group of the periodic table have similar reactivities and will not displace each other in compounds.Option 4 , no reaction is correct answer.
Step-by-step explanation:
The result of mixing lithium (Li) with sodium fluoride (NaF) will be no reaction. Both Li and Na are in the same group on the periodic table, and Li cannot replace Na in NaF because they are both alkali metals with similar reactivity. Consequently, we don't expect Li to replace Na (option 3) or to replace F (option 1). Also, Na cannot replace Li (option 2) because Na is already bonded to F. In summary, when Li is mixed with NaF, there will be no reaction.
The subject matter illustrates a typical scenario in chemical reactions where reactivity and the periodic table play crucial roles in determining the outcome. For example, fluorine (F) is the most reactive halogen and would not be easily displaced by another element in a compound like NaF. Likewise, since both Li and Na are alkali metals with comparable reactivity, one will not readily replace the other in a compound.
