Interpretation : Several alkaline earth metals are used in different emergency flares to be evaluated.
Concept Introduction : The elements of group 2 have two valence electrons. The elements are also called alkaline earth metals.
The alkaline earth metals have two valence electrons and give different colors on the flame test so they are used in different emergency flares.
The elements of group 2 include beryllium, magnesium, calcium, strontium, barium, and radon.
The alkaline earth metals are used in different flares due to their different color flame tests.
A container, a fuse, a bursting charge, and stars are the fireworks' four major parts.
The chemical elements required to produce brilliantly colored light are found in stars.
To get the red color in fireworks, metals like strontium and lithium are used.
To get orange, white, and green, the metals like calcium, white-hot magnesium, and barium are used.
