Question

the metal that produces
crimson red colour in flame *
Li
Na
K
Rb

Answer 1

Answer:

Li

Explanation:It imparts red colour due to different ionisation energy of alkali metals .The energy released is minimum in the case of Li and increases further

Answer 2

Answer:

The option (a) is correct. The metal that produces the crimson red color in flame is Lithium.

Explanation:

• Lithium gives the crimson red color to the oxidizing flame.
• The alkali metals and their salts gives the characteristic color to an oxidizing flame.
• This can be because the warmth from the flame excites the outermost orbital electron to the next energy level.
• When the excited electron comes back to the bottom state, there's an emission of radiation within the visible region of the spectrum.
• The alkali metals and also the color they convey to an oxidizing flame is Lithuim imparts crimson red, Sodium imparts yellow, potassium imparts violet, Rubidium imparts red violet and Caesium imparts blue.
