The normalized ground-state wavefunction of a hydrogen atom is ( )r a (1/ ) e r a 0 3 1/2 / ψ 0 = π − where a0 = 53 pm (the Bohr radius) and r is the distance from the nucleus. (a) Calculate the probability that the electron will be found somewhere within a small sphere of radius 1.0pm centred on the nucleus. (b) Now suppose that the same sphere is located at r = a0. What is the probability that the electron is inside it? You may approximate the probability of being in a small volume δV at position r by ( )r V

answer: .75 km

step-by-step explanation:

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
