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.
Can alkali metals metals cut with a knife?
Na (Sodium) is an alkali metal that can be cut with a knife.
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
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 is alkali metals and alkali earth metals?
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 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.
What groups are alkaline earth metals and the alkali metals in?
the first and second groups. alkaline earth metals: group IIA (2) [It consists with "Be,Mg,Ca,Sr,Ba,Ra"] alkali metals: group IA (1) [It consists with "Li,Na,K,Rb,Cs,Fr"]
