Alkali metals are from Group 1 of the Periodic Table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
What else can I help you with?
What are more reactive alkali metals or alkline earth metals?
alkali metals
What is the difference between the colours produced by alkali metals and calcium?
The colors produced by alkali metals are typically vibrant, ranging from lilac (lithium) to deep violet (cesium) when they burn. In contrast, calcium typically produces a more subtle orange-red color when heated, which is not as intense as the colors of 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.
What is the difference between alkali metals and alkaline earth metals?
Alkali metals are found in Group 1 of the periodic table and are highly reactive, while alkaline earth metals are found in Group 2 and are less reactive than alkali metals.
Why are alkali metals and alkaline earth metals called what they are AKA what's the difference in their names?
alkali earth metals are resistant to fire.
Why are earth alkali metals called earth alkali metals?
Alkali earth metals are named after their oxides, alkaline earth.
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.
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 the key differences between alkali metals and alkaline earth metals?
Alkali metals are in Group 1 of the periodic table and are highly reactive, while alkaline earth metals are in Group 2 and are less reactive. Alkali metals have one electron in their outer shell, while alkaline earth metals have two. Alkali metals are softer and have lower melting points compared to alkaline earth metals.
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.
