Question

2 identify the element with the greatest reactivity between fluorine (f) and barium (ba)
a it is impossible to tell with the given information
b fluorine (f)
c neither
d barium (ba)

Explanation:

Fluorine is a halogen. Halogens are highly reactive non - metals as they need only one electron to complete their octet. Barium is an alkaline earth metal. While alkaline earth metals are reactive (they lose 2 electrons to form ions), halogens are more reactive. Fluorine is the most reactive non - metal in the periodic table.

Answer:

B. Fluorine (F)
