The frequency of the radiation emitted by alkali metals in the flame test follows the other

A

`Li gt Na gtK gt Cs`

B

`Li gt K gt Na gt Cs`

C

`K gt na gt Li gt Cs`

D

`K gt Cs gt Na gt Li`

Text Solution

Verified by Experts

The correct Answer is:
D
Alkali metals can easily loose electron for an applied photoelectric effect. This due to their low ionization energy.
`therefore` The order of the radiation emitted by alkali metals is given by,
`K gt Cs gt Na gt Li`
