What alkaline earth metals has two valence electrons?
All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. Covers the elements beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr) and barium (Ba).
What element is an alkaline earth metal and in period 2?
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra)….Alkaline earth metal.

What alkali metal has 2 electron shells?
Barium
Barium (atomic number 56) has the same outer shell structure of two electrons in the s orbital, even though the internal electron structure for barium is quite complicated.
What is the valence electrons for alkali metals?
Q: Alkali metals have just one valence electron.
How many valence electrons do the alkaline earth metals possess How many valence electrons do the alkaline earth metals possess 1 2 7 6 8?
two valence electrons
All alkaline Earth metals have two valence electrons.
What is the alkali metal in period 2?
Lithium is the first alkali metal in the periodic table, and the first metal of any kind in the periodic table. At standard temperature and pressure, lithium is a soft, silver-white, highly reactive metal.
Which element is in Group 2 Period 2?
Answer: Berilium. Berilium is located in period 2 group2.
Why is Group 2 called alkaline earth metals?
The elements of Group 2 include beryllium, magnesium, calcium, strontium, barium and radium. These elements with the exception of beryllium are commonly known as the alkaline earth metals. These elements are called Alkaline Earth metals because of two reasons: Their oxides and hydroxides show basic (alkaline) natures.
Where are alkaline earth metals found on earth?
Since they have such high levels of reactivity, the alkaline earth metals never appear in their elemental state. They are often found in a compound form such as sulfates and carbonates.
How many valence electrons are in alkaline earth metals?
Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form. The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2).
How many valence electrons do alkali metals and alkaline earth metals have?
Why are alkaline Earth metals less reactive than alkali metals? A: It takes more energy to remove two valence electrons from an atom than one valence electron. This makes alkaline Earth metals with their two valence electrons less reactive than alkali metals with their one valence electron.
