What types of metals are in Group 2?
What types of metals are in Group 2?
Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A.
How many metals are there in Group 2?
six
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).
What is Group 2 known for?
The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.
What are Group 2 metals used for?
Group 2 compounds are often used to neutralise acidity. Calcium hydroxide, often known as slaked lime, is used in agriculture to neutralise acidic soil, and magnesium hydroxide is often used in indigestion tables to neutralise excess stomach acid.
What is the group number for calcium?
Group 2
Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table.
What kind of metals are in Group 2?
The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.
What are the properties of elements in Group 2?
All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2. This enables the metals to easily lose electrons, which increases their stability and allows them to form compounds via ionic bonds.
What is the electronic configuration of Group 2 metals?
The general electronic configuration of Group 2 elements is ns 2. Alkali earth metals have the capability to lose the two electrons in their outer shell. Thus, they react with other elements and form ionic compounds.
Which is more reactive group 1 or 2?
Group 2 contains soft, silver metals that are less metallic in character than the Group 1 elements. Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals.
