Percentage of uncertainty in average speed of an electron is 0.1756%.
Explanation:
Using Heisenberg uncertainty principle:
Δx = Uncertainty in position
Δp = Uncertainty in momentum
Δv = Uncertainty in average speed
h = Planck's constant =![6.626\times 10^{-34} kg m^2/s](/tpl/images/0387/5098/1767b.png)
m = mass of electron =![9.1\times 10^{-31} kg](/tpl/images/0387/5098/d6b57.png)
We have
Δx = 2 × 165 pm = 330 pm =![3.3\times 10^{-10} m](/tpl/images/0387/5098/58c4d.png)
Average orbital speed of electron = v =![=1.0\times 10^8 m/s](/tpl/images/0387/5098/24ef0.png)
