What metals produce soluble hydroxide and why?
Alkali metals like sodium, potassium, and lithium produce soluble hydroxides when they react with water because they are highly reactive and form strong ionic bonds with hydroxide ions. These hydroxides are soluble in water due to their high hydration enthalpies, which helps break down the ionic lattice of the compound and dissolve it in water.
Are alkaline-earth metals reactive?
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
What kind of information does the activity series of metal give us?
It compares how reactive the metals are It predicts if one metal will replace another metal in a compound
What do you get when you dissolve alkaline metals in water?
When alkaline metals are dissolved in water, they react vigorously to form alkaline hydroxides and release hydrogen gas. These reactions are highly exothermic and can result in the solution becoming hot or even boiling.
In water hydroxides of group 2 metals are?
The hydroxides of group 2 metals in water will form alkaline solutions due to their ability to release hydroxide ions (OH-) into the solution. This results in an increase in the pH of the solution. Examples include calcium hydroxide (Ca(OH)2) and magnesium hydroxide (Mg(OH)2).
When a metal reacts with water what are the products of the reactions?
when metals react with water they form hydroxides

Elements in the preodic table which forms a basic oxide?
Elements on the left side of the periodic table, such as alkali metals like sodium and alkaline earth metals like calcium, tend to form basic oxides. These elements have low electronegativity and readily lose electrons to form positively charged ions, which react with oxygen to form basic oxides.
Are alkaline-earth metals reactive?
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
What kind of information does the activity series of metal give us?
It compares how reactive the metals are It predicts if one metal will replace another metal in a compound
Which group in the periodic table contains an element that can form a blue sulfate compound?
I believe it is group 11 since it is a group in the transition metal class, and transition metals form ions with color.
What do you get when you dissolve alkaline metals in water?
When alkaline metals are dissolved in water, they react vigorously to form alkaline hydroxides and release hydrogen gas. These reactions are highly exothermic and can result in the solution becoming hot or even boiling.
Why are neither theh alkali metals nor the alkaline-earth metals found uncombined in nature?
Due to their very high reactivity with oxygen and also water, they combine to form oxides, hydroxides and from there to carbonates and others.
In water hydroxides of group 2 metals are?
The hydroxides of group 2 metals in water will form alkaline solutions due to their ability to release hydroxide ions (OH-) into the solution. This results in an increase in the pH of the solution. Examples include calcium hydroxide (Ca(OH)2) and magnesium hydroxide (Mg(OH)2).
What is formed when two metals or a metal and nonmetal are combined?
When two metals are combined, they form an alloy, which is a solid solution of different metals. When a metal and a nonmetal are combined, they form an ionic compound through the transfer of electrons between the two elements.
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.
