Basics of Hydrogen Atom

What is the simplest atom in the universe?

• Hydrogen

• Helium

• Carbon

• Nitrogen

Which wavefunction describe the shape of of the orbital

• Angular Wavefunction

• Radial wavefunction

• total wavefunction

• None of these

Which quantum number distinguishes between different orbitals within the same energy level?

• Principal quantum number (n)

• Angular momentum quantum number (l)

• Magnetic quantum number (ml)

• Spin quantum number (ms)

How will you define an Orbital?

• The place where finding the electron probability is maximum.

• They are just single electron wavefunction

• There is no defination for orbital

• None of the above

If the orbital are single electron wavefunction then how many wavefunction is needed for 2 electron?

• One

• Two

• Two electron dont have wavefunction

I am studying the hydrogen atom using the Schrödinger equation, and I am interested in calculating the electron density with respect to the distance. Which wavefunction should I use?

• Total Wavefunction

• Radial Wavefunction

• Angular Wavefunction

• Can not be calculated.

I am studying the hydrogen atom using the Schrödinger equation, and I am interested in calculating the electron density with respect to the orientation of the electron (the angle). Which wavefunction should I use?

• Radial

• Angular

• Total

• None of the these

If the hydrogen electron is in n=3 state then how many degenerate state is possible?

• 11

• 3

• 9

• 5

The energy of electron in a hydrogen atom depends on

• "n" and "l" quantum No.

• "n" quantum No.

• "l" quantum No.

• None of the these.

Which atomic orbital has the highest energy?

• 1s

• 2s

• 3p

• 3d
