Which properties of alkali metals unusual metals?
Alkali metal forms Alkali while metals form bases.
What are more reactive alkali metals or alkline earth metals?
alkali metals
Are alkali metal and alkaline earht metals similar?
The alkali earth metals act in a similar but slightly less reactive way to alkali metals
Why alkali metals are kept in kerosene?
Why. Alkali. Metals are kept. In kerosene
What are elements called in group 1?
Alkali metals
Is sodium bromide ionized or dissociated in an aqueous solution?
Yes, it is an ionic compound of Alkali metal and all alkali metals salts are ionize-able in water.
What color are main group metals as solids and in solution?
Main group metals are generally a silvery color and caesium has a goldy tinge. In aqueous solution they are all colorless. (In this respect they can be contrasted to the metals copper, gold which are very colored in the metallic state- and with transition metals in aqueous solution which can often be colored where they have have d electrons that can be excited by light leading to absorption of some frequancies giving a color. Alkali metals (sodium, potassium etc in group 1) dissolve in liquid ammonia to give an intense bright blue color- due to ionisation and relase of an electron into solution.
Lithium is better reducing agent than cesium in aqueous solution?
, the alkali metals are powerful reducing agents. Lithium in aqueous solution is as strong a reducing agent as Caesium. This is probably due to high hydration energy of small lithium ion, which compensates for high ionisation energy. The hydration energy of alkali metal ions follows the order: Li+ > Na+ > K+ > Rb+ > Cs+ . Due to extensive hydration, Li+ ion has the highest hydration energy, as a result of which reduction potential of Li is higher than other alkali metals. Thus most powerful reducing agent in solution is lithium.
Why Group1A metals are powerful reductants in aqueous solution?
One definition of "reduction" in chemistry is gaining electrons, and alkali metals readily give up their single valence electrons to another more electronegative atom. In fact, neutral group 1A atoms are so reductive that they can not exist for long in aqueous solutions and will displace hydrogen gas from the water molecules unless there is some other substance even more easily reduced in the solution.
Compound that forms hydroxide ions in solution?
Hydroxide salts from (mainly) alkali and some earth-alkali metals.
Which group above 9-12 reacts with water to yield alkaline solution?
These are the alkali metals.
Why can't metals that are high on the activity series like calcium be precipitated from aqueous solution?
because they cant
Which properties of alkali metals unusual metals?

How chemically active are alkali metals?
Alkali metals are the most reactive metals.
What are more reactive alkali metals or alkline earth metals?
alkali metals
How are alkali metals different any from other metals?
Alkali metals are very reactive metals.
How do alkali metals react with other alkali metals?
They don't
