Alkali metals are in the first column of the Periodic Table, but do not include Hydrogen.
The alkali metal family is composed of Lithium, Sodium, Potassium, Rubidium, Cesium and Francium.
An example of an alkali metal is Sodium (Na).
What else can I help you with?
What are more reactive alkali metals or alkline earth metals?
alkali metals
Is helium in the alkali metals or alkali earth metals?
neither. it is a noble gas
What are the classes of elements on the periodic table?
non-metals .... alkali metals....transition metals....alkali earth metals....rare earth metals....other metals....halogens....inert elements
Are The rare earth metals are a category of the alkali metals?
No.
Which elements is most reactive alkali metals or alkali earth metal or carbon family or inert gases?
alkali metals
Why are earth alkali metals called earth alkali metals?
Alkali earth metals are named after their oxides, alkaline earth.
Is alkali the only earth metal?
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
What are more reactive alkali metals or alkline earth metals?
alkali metals
Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?
Alkaline earth metals do not exist , only alkali earth metals
Is Na a alkali earth metals?
No,it is not a alkali earth metal.It is a alkali metal.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
How are the alkali metals different from the alkali earth metals in the periodic table?
The alkali metals have a valence of 1 while the alkaline earth metals have a valence of 2. The alkali metals are generally lighter, softer, more reactive, and have lower melting points than the alkaline earth metals.
How are the alkali metals different from the alkali-earth metals in the periodic table?
The alkali metals have a valence of 1 while the alkaline earth metals have a valence of 2. The alkali metals are generally lighter, softer, more reactive, and have lower melting points than the alkaline earth metals.
What is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
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 alkali metals next to the alkali earth metals?
yes, the metals are next to each other
Is helium in the alkali metals or alkali earth metals?
neither. it is a noble gas
