Question

when a highly reactive metal, such as lithium (li), is mixed with a highly reactive non - metal, such as chlorine (cl), they will most likely combine to form lithium chloride (licl). based on the trends of the periodic table, which other element is likely to combine with lithium?
a. neon (ne)
b. calcium (ca)
c. fluorine (f)
d. silver (ag)

Explanation:

Lithium is a highly reactive metal. Non - metals tend to react with metals. Fluorine (F) is a highly reactive non - metal. Neon (Ne) is a noble gas and very unreactive. Calcium (Ca) is a metal and metals don't combine with other metals in the same way as metals and non - metals do. Silver (Ag) is also a metal. So, fluorine is likely to combine with lithium.

Answer:

C. Fluorine (F)
