The alkaline earth metals are in Group 2 on the Periodic Table. They are beryllium, Be, magnesium, Mg, calcium, Ca, strontium, Sr, barium, Ba, radium, Ra. These are not to be confused with the alkali metals, which are in Group 1 on the periodic table.
What else can I help you with?
How does the density of the alkaline earth metal compare with alkali metal?
The density of alkaline earth metals is generally higher than that of alkali metals. This is because alkali metals have only one valence electron and are larger in size compared to alkaline earth metals, which have two valence electrons and are smaller in size. The higher density of alkaline earth metals is due to their more compact atomic structure.
What state are most alkaline earth metals?
Most alkaline earth metals are in a solid state at room temperature.
What is the family name that calcium is in?
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
What Family does beryllium belong to?
Beryllium belongs to the alkaline earth metals family on the periodic table.
How did alkaline earth metals get their names?
Alkaline earth metals were named "earth" to differentiate them from alkali metals, which were known to form alkaline solutions when reacting with water. The term "alkaline" was added to indicate they were compounds with a high pH.
What is group two of metals?
the alkaline earth metals
What is group two metals?
the alkaline earth metals
Name two elements that are alkaline earth metals?
Two elements that are alkaline earth metals are calcium and magnesium.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
How many valence electrons in alkaline earth metals?
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
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.
Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
Do all alkaline metals have 2 electron shells?
No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.
Which family has 2 electrons in outer shell?
alkaline earth metals such as Be, Mg, Ca, Sr, Ba, Ra
In what ways do alkali metals and alkaline earth metals differ?
Alkali metals and alkaline earth metals differ in their reactivity and properties. Alkali metals are more reactive and have one electron in their outer shell, while alkaline earth metals are less reactive and have two electrons in their outer shell. Additionally, alkali metals are softer and have lower melting points compared to alkaline earth metals.
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 elements have two valance electrons?
alkaline earth metals
