What is a alkaline earth metal element?
The alkaline earth metals are the second most reactive family of elements. Beryllium, magnesium, calcium, strontium, barium and radium are all shiny, and silvery-white. They all have low densities, melting points and boiling points, and they tend to form solutions with a pH greater than 7.
What contains an alkaline earth metal?
alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
What color are alkaline earth metals usually?
silvery-white
The alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure. All the alkaline earth metals readily lose their two outermost electrons to form cations with a 2+ charge.
What alkaline earth metal is used in flashbulbs?
Alkaline Earth Metals Uses Apart from radium, the Alkali earth metals are also used in flashbulbs and batteries. Radium, being a highly radioactive element, does not have any industrial applications at present.
Which of the following are alkaline earth metals?
The six elements in column 2 of the Periodic table are called Alkaline Earth Metals. These include Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra).
Where are alkaline earth metals found?
Group II
You will find the alkaline earth metals right next door in Group II. This is the second most reactive family of elements in the periodic table. Do you know why they are called alkaline? When these compounds are mixed in solutions, they are likely to form solutions with a pH greater than 7.
Which element was used in flashbulbs?
Magnesium
Magnesium is used in flash bulbs. When magnesium burns it makes a very bright, white light.
