keep in mind that hf is just the power of 1 photon. maybe not two. maybe not three. one.  1) 5.12 * 10^3 photons  discover the power of 1 photon, after that regulate how numerous photons are expected to attain the sensitiveness.  age = hf  = (6.626 * 10^-34 js)(5.95 * 10^19 hz)  = 3.94247 * 10^-14 j per photon  (2.02 * 10^-10 j) / (3.94247 * 10^-14 j/photon) = 5123.69149 photons  round to 3 sig figs.  2) 5.77 * 10^-17 j  power of pulse = power per photon * few photons  = hfn  = (6.626 * 10^-34 js)(1.66 * 10^13 hz)(5250)  = 5.774559 * 10^-17 j  round to 3 sig figs.  3) 4.07 * 10^8 kj/mol  10^12 pm = 1 m  c = fλ  f = c/λ  age = hf  = hc/λ  = [(6.626 * 10^-34 js)(3.00 * 10^8 m/s) / (2.94 * 10^-12 m)](1 kj/1000 j)(6.02 * 10^23 photons/mol)  = 40702571.4 kj/mol  round to 3 sig figs.  4) 9.94 * 10^-1 m  age = hc/λ  λ = hc / age  = (6.626 * 10^-34 js)(3.00 * 10^8 m/s) / (2.00 * 10^-25 j)  = 0.9939 m  round to 3 sig figs.  5) 9.06 * 10^3 photons  power of pulse = power per photon * few photons  few photons = power of pulse / power per photon  = power of pulse / (hf)  = (3.87 * 10^-13 j) / [(6.626 * 10^-34 js)(6.45 * 10^16 hz)]  = 9055.23695 photons  round to 3 sig figs.  6) 2.78 * 10^-15 j  it is issue 1, except backwards.  sensitiveness = minumum few photons * power per photon  = (5930)(6.626 * 10^-34 js)(7.077 * 10^14 hz)  = 2.78070758 × 10^-15 j  round to 3 sig figs.

the witnessing the electric setup we are able to state the factor is fluorine. fluorine is considered the most electronegative aspect in the regular dining table. but by just witnessing the setup we can’t state about its reactivity because we do not determine if its setup after excitation or by inclusion of electrons. however if maybe not after that, it will be the lightest halogen and is out there as an extremely poisonous pale-yellow diatomic fuel at standard problems. as the utmost electronegative factor, it is very reactive: practically all various other elements, including some noble fumes, form substances with fluorine.
