Respuesta :
B. Fluorine.
Chlorine and Fluorine are in the same period which means they have similar properties and reactivity.
Answer: Option (B) is the correct answer.
Explanation:
Lithium is an alkali metal with atomic number 3 and its electronic distribution is 2, 1.
So, in order to attain stability it needs to lose its one valence electron and thus it becomes [tex]Li^{+}[/tex] ion.
Hence, an ionic bond will always be formed when a metal reacts with a non-metal. As atomic number of fluorine is 9 and its electronic configuration is 2, 7.
So, fluorine on gaining one electron from lithium will form LiF compound.
Whereas neon is a noble gas so it will be unreactive in nature and silver and calcium being metals will not be able to combine with lithium which is also a metal.
Thus, we can conclude that fluorine (F) is the element which is likely to combine with lithium.
