4. Determine the wavelength, in m, of an electron (m, = 9.11 x 1031 kg, having a velocity of 5.65 x 107 m/s. Recall that Planck's constant (h) = 662 x 1034 J.s. Super extra credit: what is the wavelength of a valence electron on U, viz., find the approximate velocity of the ith electron. Hint: you will not be using the formula you will be needing above, but it will not require any extraordinary math either. 5. Give me the most likely name of the theoretical molecule and the oxidation state of the cen- tral atom for HAtO,

Explanation / Answer

we have the formula,

wave length = h/mV

h = plancks constant

m = mass of the electron

V = velocity of electron

Wave length = 6.62 * 10^-34 J.S/((9.11*10^-31 kg)*(5.65*10^7m/s))

wave length = 1.2861 * 10^-11 m
