Look at any Periodic Table:
Beryllium #4
Magnesium #12
Calcium #20
Strontium #38
Barium #56
Radium #88
Beryllium.
The alkaline earth metals are the group 2 elements (on the periodic table). Beryllium is the lightest of them.
The most metallic element is Francium, so the least metallic alkaline earth metal would be the one farthest away from Francium on the periodic table: Beryllium, Be.
Be is the least reactive of alkaline earth metals. It is the first metal of the alkaline earth metals.

Least reactive alkaline earth metal?
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
Metals that are less reactive than alkaline metals and alkaline earth metals are called what?
The periodic table goes from left to right if your looking for re-activity (with the exception of hydrogen). Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are the most reactive elements. The Noble gases are the least reactive elements which include Argon, Neon, Helium, Krypton, Xenon, Radon, and (arguably) Ununoctium. Hope that helps!
What makes the earth the angry?
Pollution makes the Earth angry. At least, in a metaphorical sense.
What zone receives the least sunlight?
the earth's core
How many families are on the earth?
how many families of at least two people living together are on the earth
Is lithium a alkaline earth metal?
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
Least reactive alkaline earth metal?
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
Are all alkaline earth metals reactive?
Yes, all alkaline earth metals are reactive because they have two electrons in their outer shell, making them prone to forming bonds with other elements to achieve a stable electron configuration. However, their reactivity varies among the alkaline earth metals, with beryllium being the least reactive and barium being the most reactive.
What is the order of reactivity of alkaline earth metals?
The order of reactivity of alkaline earth metals decreases down the group. This means that the reactivity decreases as you go from beryllium to radium. Beryllium is the least reactive, while radium is the most reactive.
Is chlorine the most or least reactive of all elements?
Neither. Chlorine is among the most highly reactive nonmetal elements, but fluorine and oxygen are even more reactive, as are the heavier alkali and alkaline earth metals.
Which element is alkaline earth element with the least massive atoms?
Beryllium is the alkaline earth element with the least massive atoms.
Why is beryllium the least reactive?
Beryllium is the least reactive alkali earth metal because it has a stable electron configuration with two electrons in its outer shell. This makes it reluctant to lose or gain electrons to form compounds. Additionally, beryllium forms a protective oxide layer on its surface when exposed to air, which further decreases its reactivity.
Metals that are less reactive than alkaline metals and alkaline earth metals are called what?
The periodic table goes from left to right if your looking for re-activity (with the exception of hydrogen). Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are the most reactive elements. The Noble gases are the least reactive elements which include Argon, Neon, Helium, Krypton, Xenon, Radon, and (arguably) Ununoctium. Hope that helps!
What is the important characteristic do the alkali and alkaline earth metals have in common?
they all have at least one electron
What part of the periodic table is the most reactive and least reactive?
The most reactive elements are located in the alkali metals group on the far left side of the periodic table. The least reactive elements are the noble gases, found in the far right group.
What are the least reactive noble gases or metalloids?
noble gases are least reactive
Is potassium the least reactive?
no, it is very reactive.
