Use the Rydberg equation to calculate the wavelength (in nm) of the photon emitted when a hydrogen atom undergoes a transition f

natka813 [3]

Answer:

The answer is 434nm

Explanation:

The Rydberg equation is an empirical relationship expressed by Balmer and Rydberg which is stated as:

1/λ = $R_{H} (\frac{1}{n_{f} ^{2} }-\frac{1}{n_{i} ^{2} } )$ .............................. (1)

where λ is the wavelength, $R_{H}$ is the Rydberg constant equal to $1.097 x 10^{7}m^{-1}$ , n is the transition level number, the subscript f and i are the final and initial levels respectively. Therefore for final transition n = 2 and for initial transition n = 5.

Making substitutions into equation (1), gives

1/λ = $1.097 x 10^{7} (\frac{1}{2^{2} }-\frac{1}{5^{2} })$

= $1.097 x 10^{7} (\frac{1}{4} - \frac{1}{25} )$

= $1.097 x 10^{7} (0.25 - 0.04)$

= $1.097 x 10^{7} x 0.21$

= 2303700

∴ λ = $\frac{1}{2303700}$ $= 4.34 x 10^{-7}m$

Converting to nm, we have

λ = $\frac{4.34 x 10^{-7} }{10^{-9} } = 434nm$

Therefore, the wavelength of the emitted photon is 434nm

A nitride ion has 7 protons, 8 neutrons, and 10 electrons. What is the overall charge on this ion?

xz_007 [3.2K]

The correct answer is: -3 (minus three)

Explanation:
To find the overall charge, we add electrons and protons. Make sure that you use the negative sign for an electron and positive sign for proton.

There are 10 electrons. It means the charge is "-10"
There are 7 protons. It means the charge is "+7"

Add both of them:

+7 - 10 = -3

Therefore the overall charge on this ion is -3.

What is the wavelength of spectral line resulted from the electron transition from n=3 to n=2 in a hydrogen atom.

MakcuM [25]

Answer:

$\lambda=6.56x10^{-7}m$

Explanation:

Hello there!

In this case, it possible to use the Rydberg equation in order to calculate the wavelength for this transition from n=3 to n=2 as shown below:

$\frac{1}{\lambda} =R_H(\frac{1}{n_f^2}-\frac{1}{n_i^2} )$

Thus, we plug in the corresponding energy levels and the Rydberg constant to obtain:

$\frac{1}{\lambda} =10973731.6m^{-1}(\frac{1}{2^2}-\frac{1}{3^2} )\\\\\frac{1}{\lambda} =1524129.4m^{-1}\\\\\lambda=\frac{1}{1524129.4m^{-1}} \\\\\lambda=6.56x10^{-7}m$

Best regards!
