The ionization enthalpy of K and Cs is less than that of Li and therefore these metals
easily lose electrons on exposure to light than lithium.That's the reason potassium and
cesium are used in photoelectric cells rather than Cs.

∙ 11y agoCaesium and potassium have low work functions. As a result, when these metals are irradiated with light, the light energy absorbed may be sufficient to make these metals emit electrons (photoelectric effect). This property makes caesium and potassium useful as electrodes in photoelectric cells.

What chemical is burning when you see a violet purple flame?
potassium permanganate is purple in colour and is used for cleaning.
What is cesium used for?
On clock dials to flouresce in the dark. It is also used in the atomic clock. Cesium formate is sometimes used in oil drilling.
What uses does caesium have?
Caesium (also called cesium) is used in photoelectric cells, as a catalyst for hydrogenation of some organic compounds, in medical applications, and in industrial research. Other uses of caesium include atomic clocks, removing air traces from vacuum tubes, and in ion propulsion systems.
What is cesium chloride used for?
It is used to help with the pain of cancer.
Is rubidium used in photoelectric cells?
This application is probably possible.
What is radioisotopes potassium-40 and its uses?
is used in photoelectric cells.
What was albert einsteins's contribution to our understanding of the photoelectric effect?
He wrote a paper that described the photoelectric effect. The paper contained equations used to explain why certain wavelengths of light cause the p-e effect but others do not and the energy changes in the electrons during the p-e effect.
Who developed the theory of photons being quantized?
Einstein, and he used the theory to describe the photoelectric effect.
What is the most common use for caesium?
Caesium (Cesium in American English), one of three metals that is in the liquid form at room temperature is most commonly used in atomic clocks. Historically, the most important use for cesium has been in research and development, primarily in chemical and electrical applications. It is also used in photoelectric cells.
What chemical is burning when you see a violet purple flame?
potassium permanganate is purple in colour and is used for cleaning.
How do photocells generate electricity?
the photoelectrons released during photoelectric effect are used to generate electricity in photo cells

Why are potassium and caesium rather than lithim used in photoelectric cells?
Potassium can loose electron easily . Comparatively Lithium have high ionisation energy and low level of loosing electron while absorbing light energy.
Why are the elements cesium and rubidum used in many atomic clocks?
The element that is used in Cesium. Usually it will come in the form of Cesium 133 because this is the most easily used form.
On what factors does photoelectric current depends?
photoelectric current depends on intensity of light used
Element used in photoelectric cells and in atomic clocks?
abcdefghijklmnopqrstuvwxyz
What is applications of photoelectric effect in our daily life?
It is in the digital cameras, image sensors, and night vision devices that are widely used in the present world.
