Embibe Experts Solutions for Chapter: Structure of Atom, Exercise 1: Level 1

The ionization enthalpy of the hydrogen atom is $1.312\times {10}^6 \mathrm{J}/\mathrm{mol}$. The energy required to excite the electron in the atom from $\mathrm{n}=1$ to $\mathrm{n}=2$ is:

In Bohr's orbit, what is the ratio of the total kinetic energy and the total energy of the electron?

The kinetic energy of an electron accelerated from rest through a potential difference of $5\mathrm{V}$ will be:

According to Bohr's theory, the energy required for the transition of electron in $\mathrm{H}$-atom from $\mathrm{n}=6$ to $\mathrm{n}=8$ state is

The wave number of the first emission line in the Balmer series of $\mathrm{H}$-Spectrum is:

($\mathrm{R}=$ Rydberg's constant)

In a given atom, no two electrons can have the same values for all the four quantum numbers. This is called

For azimuthal quantum number $\mathrm{l}=3$, the maximum number of electrons will be

Which of the following should be the possible subshells for $\mathrm{n}+\mathrm{l}=7$?
