Be is least reactive its outermost orbital 2s is completely filled so its electron affinity is almost zero.
magnesium (Mg)
chlorine
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
noble gases are least reactive
Beryllium is the least reactive in the group 2.
magnesium (Mg)
No, Li and Mg are not capable of displacing each other in a single replacement reaction because Li is less reactive than Mg. Therefore, LiCl + MgCl2 will not undergo a single replacement reaction.
chlorine
From greatest to least tendency to accept an electron, they are F, O, C, Li, and Be.
Lithium, (Li) element three and the least reactive of the alkali metals group.
Lithium is more reactive.
Helium is least reactive element.It forms no compounds.Platinum is least reactive metal.
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.

B-Al is different from the other pairs because it consists of elements from different groups in the periodic table. Li-Mg, Na-K, and Ca-Mg are pairs of elements from the same group which exhibit similar chemical characteristics.
Neon (Ne) is less reactive than Lithium (Li) because neon is a noble gas with a full outer electron shell, making it very stable and nonreactive. In contrast, lithium is a highly reactive metal that readily loses its outer electron to form stable compounds.
