Seema Saini Solutions for Chapter: Atomic Structure, Exercise 2: DPP 3.2

Suppose that a hypothetical atom gives a red, green, blue and violet line in the spectrum. Which jump according to figure would give off the red spectral line?

For the following transitions in hydrogen-like atoms, select the correct relation(s):

$$\begin{gathered} \mathrm{\nu }=\text{frequency of the emitted radiation} \\ \mathrm{\lambda }=\text{wavelength of the emitted radiation} \end{gathered}$$

If the electron of the hydrogen atom is replaced by another particle of the same charge but of the double mass, then:

Let $\mathrm{r}, \mathrm{v}$ and $\mathrm{E}$ are the radius of the orbit, speed of the electron and the total energy of the electron, respectively. Which of the following quantities are proportional to the quantum number ${}^{\text{'}}\mathrm{n}^{\text{'}}?$

Select the correct statements for hydrogen like atoms or ions.

An electron in a hydrogen atom makes a transition from $\mathrm{n}={\mathrm{n}}_1$ to $\mathrm{n}={\mathrm{n}}_2.$ The time period of the electron in the initial state is eight times that in the final state. What are the possible values of ${\mathrm{n}}_1$ and ${\mathrm{n}}_2?$

Identify the correct statement(s) from the following:

A hydrogen-like atom has ground state binding energy $122.4 \mathrm{eV}$. Then:
