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 is solubility order of sulphate of alkaline earth metal?
The solubility order of alkaline earth metal sulfates generally decreases as you move down the group in the periodic table. Thus, the solubility trend is: magnesium sulfate (MgSO₄) and calcium sulfate (CaSO₄) are relatively soluble, while strontium sulfate (SrSO₄) is moderately soluble, and barium sulfate (BaSO₄) is largely insoluble. Therefore, the overall order of solubility from most to least soluble is MgSO₄ > CaSO₄ > SrSO₄ > BaSO₄.
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
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 list has the classes of elements in order from most reactive to least reactive?
The order of reactivity among classes of elements typically follows this pattern: alkali metals (most reactive), alkaline earth metals, transition metals, metalloids, nonmetals, and noble gases (least reactive). Alkali metals, such as lithium and sodium, readily lose electrons, making them highly reactive, especially with water. Alkaline earth metals are also reactive but to a lesser extent, while noble gases are largely inert due to their complete electron shells.
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?
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!
Which element would be LEAST reactive with oxygen?
Noble gases, such as helium or neon, would be the least reactive with oxygen due to their full valence electron shells, which make them stable and unlikely to form compounds. Among other elements, metals like gold and platinum also exhibit low reactivity with oxygen, as they do not readily oxidize. In contrast, alkali and alkaline earth metals are highly reactive with oxygen.
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.
