If titanium is irradiated with light of 233 nm, what is the maximum possible kinetic energy of the emitted electrons? what is the maximum number of electrons that can be freed by a burst of light whose total energy is 2.00 μj.

= 2.346 x 10^12 electrons.

The energy of each photon can be obtained using Planck's equation:  

E = hν = (hc)/λ

   = (6.626 x 10^-34 J s)(2.9979 x 10^8 m/s) / (233 x 10^-9 m)

   = 8.525 x 10^-19 Joules

The maximum kinetic energy for each freed electron will be;

 =  8.525 x 10-19 J - 6.94 x 10^-19 J

  = 1.585 x 10^-19 J

The number of 233 nm photons in the 2.00 x 10-6 J burst of light will be;

= 2.00 x 10^-6 J / 8.525 x 10^-19 J

= 2.346 x 10^12 photons.

Each photon can free at most one electron, so the maximum number of freed electrons will be 2.346 x 10^12 electrons.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
