What else can I help you with?
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?
Compared to what? But it would be less reactive because the s orbital is filled, the electrons are all paired. If you mean "Why is beryllium the least reactive of the Group II alkaline earth metals?", then this is because it has the least electron shielding, having an electron configuration of 2, 2. Beryllium is at the top as the first of the Group II alkaline earth metals, and reactivity increases as you go down Groups I and II.
Metals that are less reactive than alkaline metals and alkaline earth metals are called what?

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 alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
What are the least reactive noble gases or metalloids?
noble gases are least reactive
Is potassium the least reactive?
no, it is very reactive.
