What is the maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light? The threshold wavelength for a silver metal surface is 267 nm.
Give your answer accurate to three significant figures. Use exponential notation (e. g. 1.23e-19).

The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe=hf−BE KE e = h f − BE , where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.

Explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

you need to have a picture of the atom that way we can answer it
