Alkali metals and alkaline-earth metals react violently with water or air because they have low ionization energies, meaning they readily lose electrons to form positive ions. When they react, they release a large amount of energy as heat and produce hydrogen gas. This rapid release of energy and gas can result in explosions or violent reactions.
What else can I help you with?
Is alkaline soluble?
Alkaline substances are generally not soluble in water, but they may be soluble in other solvents depending on their chemical composition. Alkaline substances often form salts that are soluble in water.
Alkaline-earth metal do not react with oxygen?
Alkaline-earth metals do react with oxygen, forming oxides. The reaction tends to be less vigorous compared to alkali metals, as alkaline-earth metals have a higher ionization energy. Examples of alkaline-earth metal oxides include magnesium oxide (MgO) and calcium oxide (CaO).
Is alkaline flammable?
Alkaline substances are generally not flammable on their own. However, certain alkaline metals such as lithium, sodium, and potassium can react violently with water or air, leading to combustion. These reactions are highly exothermic and can produce flammable hydrogen gas.
What chemical will burn violently when mixed with water but not with kerosene?
Sodium and potassium metals will burn violently when mixed with water, forming alkaline hydroxides and hydrogen gas. When mixed with kerosene, a hydrocarbon mixture, the reaction does not occur as kerosene is not reactive with these metals.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
Is alkaline soluble?
Alkaline substances are generally not soluble in water, but they may be soluble in other solvents depending on their chemical composition. Alkaline substances often form salts that are soluble in water.

Alkaline-earth metals do react with oxygen, forming oxides. The reaction tends to be less vigorous compared to alkali metals, as alkaline-earth metals have a higher ionization energy. Examples of alkaline-earth metal oxides include magnesium oxide (MgO) and calcium oxide (CaO).
What metal could explode if you reacted it with an acid?
All the alkaline metals will explode violently when exposed to H2O. The further down you go on the Periodic Table of the elements, the more reactive they become.(Hope this helps!)
Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
Is alkaline flammable?

Is alkaline earth metal in the group of metals nonmetals metalloids or diatomic molecule?
The alkaline earth metals are metals!
How many Alkaline and Alkali Metals are there?
Six alkali metals and six alkaline earths.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
What are the key differences between alkaline earth metals and alkali metals?
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
Are all alkaline earth metals metals?
no
