Which 2 metals are most reactive?
Potassium and sodium are the two most reactive metals in the periodic table. They can react vigorously with water and air to form compounds.
Which two families in the periodic table have the most reactive metals?
The alkali metals (Group 1) and the alkaline earth metals (Group 2) are the two families in the periodic table with the most reactive metals. Alkali metals are more reactive than alkaline earth metals due to their lower ionization energy and higher reactivity with water and air.
Sodium is under water metal?
No sodium is an extremely reactive metal that reacts violently with water. Sodium is in fact one of only two metals that is less dense than water, meaning that it can float on water. Whether a metal is underwater or not does not change its identity.
Two metals that will float on water and react very quikly to form an alkalis?
Such metals are Sodium and Potassium (and all the alkali metals).
Which two substances can be to compare the reactivity of metals other than acids?
Water and oxygen can be used to compare the reactivity of metals. More reactive metals will react with water to form metal hydroxides and hydrogen gas, and with oxygen to form metal oxides. Less reactive metals may not react with water or oxygen at all.
What are the two very reactive non metals?
They are: fluorine and oxygen.
Is it true that transition metals are less reactive than the metals in group one and two of the periodic table?
True
What is the similarities between alkali metals and alkaline earth metals?
AM are in group one and are very reactive, unstable, and has one electron in the outer shell, where as in AEM they are in group two and have 2 electrons in the outer shell.
How reactive are alkaline earth metals?
Alkaline earth metals are less reactive than alkali metals, but more reactive than transition metals. They readily form 2+ cations in chemical reactions due to their tendency to lose two electrons. Their reactivity increases down the group as the atomic radius increases.
How are alkali metals different from alkaline metals?
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
The two most reactive groups of elements in the periodic table are the alkali metals and the what?
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
How are alkaline earth metals different from alkali metals in terms of their properties and reactivity?
Alkaline earth metals have higher melting points and densities compared to alkali metals. They are less reactive and have two valence electrons, while alkali metals have one valence electron and are more reactive.
