Question

An alkaline earth metal is more reactive than an alkali metal. *

Answer 1

an alkaline

Step-by-step explanation:

when valence electrons are farther from the nucleus, they are attracted less strongly by the nucleus an more easily remove from the atom .this makes the atom more reactive .this make alkaline metal with their two valence electron less reactive than alkali metal with their one valence electron

Answer 2

Because of this charge increase, the atoms of the alkaline earth metals are smaller and have higher first ionization energies than the alkali metals within the same period. The higher ionization energy makes the alkaline earth metals less reactive than the alkali metals; however, they are still very reactive elements
