Why are group 2 metals classified as alkaline earth metals?
Group 2 metals are classified as alkaline earth metals because they share similar properties: they are shiny, silvery-white, relatively reactive metals with two electrons in their outer shell. They react with water to form alkaline solutions and are generally less reactive than the alkali metals in Group 1.
Are metals always shiny?
No. None of the Group 1 and Group 2 elements of the periodic table, the alkali and alkali earth metals respectively, stay shiny when exposed to air. They all react with moisture in air, and they tarnish quickly. A number of other metals will not stay shiny, either. Iron can be polished, but it will oxidize (rust) if left in air. Some metals will not react with air or the moisture in it, and some will. The results are mixed in that there are a lot of transition metals (Groups 3 through 12 on the periodic table), and each one would have to be evaluated independently (or with its "group mates") to discover if it would stay shiny. Links are provided to some relevant Wikipedia articles. The links are to the groups of metals, and each element in the Group chart is a hyperlink to that element. It should make it easy to do a quick search of the metals to get a complete answer, if that is what is desired.
What are the elements in group 2a called?
The elements in group 2A are called alkaline earth metals. They include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are shiny, silvery-white metals that are reactive and have two electrons in their outer shell.
What statement about metals true?
Metals are typically shiny, malleable, and good conductors of electricity.
What is true about all of the alkaline-earth-metals?
They are in the s block. less reactive than 1st group.
What group of elements are soft silver-white and shiny metals?
These are the alkali metals.
Which element group is made up of shiny solids that are harder than alkali metals?
The group you're referring to is the group of alkaline earth metals. They are shiny solids that are harder than alkali metals. Examples include calcium, magnesium, and barium.
Are all non-metals shiny?
Non-metals are not normally shiny.
Are Group 7A elements the alkaline earth metals?
No, Group 7A elements are the halogens - a highly reactive group of nonmetals. Alkaline earth metals are found in Group 2A of the periodic table and are characterized by being shiny, silvery-white metals that react readily with water.
What is the shiny appearance of metals?
There are quite a few metals that are shiny including gold. Silver and titanium are also metals that are shiny when polished.
What do group 1 metals look like?
Group 1 metals, such as lithium, sodium, and potassium, are shiny, soft metals with a silvery appearance. They are highly reactive and tend to tarnish quickly when exposed to air, forming a dull oxide layer on the surface. Group 1 metals are typically stored under oil to prevent them from reacting with moisture and oxygen in the air.
Are alkali metals shiny gray solids soft?
yes if you cut inside it you will see all of this descriptions
Are alkali metals metal non metal or metall oid?
No, they are metals. Perhaps you are thinking of their dried salt crystals.
What metal container will maintain heat longer shiny inside and outside or shiny inside and black outside?
If your container is mirror finish on both sides, it will be a better insulator.There is a thermal concept known as emissivity, which is closely related to the inverse of reflectivity.
What is a group of shiny conductors?
A group of shiny conductors is called a cluster or a collection of metals that are good conductors of electricity, such as copper, silver, and gold. These metals have high electrical conductivity due to the free movement of electrons within their atomic structure.
What similarities exist among the shells diagrams for the alkali metals?
They down in a verticle column. this is representing a family or group of chemicals lol
Which side is inside if you are baking fish in tin foil?
The "inside" of tin foil is the dull side. The "outside" of tin foil is the shiny side.
