Questions on structure of atom from ncert and from previous competitive exams like JEE( Mains, Advanced) , NEET etc.
In this video we will cover:-
1.Numerical 1:- Uncertainty in the position of an electron (mass = 9.1 x 10-34 kg) moving with a velocity 300 m s-1 , accurate up to 0.001%, will be: (h= 6.63 x 10-34 J s)
2. Numerical 2:- The charge of an electron is -1.6 x 10-19 C. The value of free charge on Li+ ion will be?
3.Numerical 3:- The radius of the second Bohr orbit for hydrogen atom is (Planck's Const. h=6.6262×10−34 Js, mass of electron = 9.1091×10−31 kg , charge of electron e=1.60210×10−19C, permittivity of vacuum ∈0=8.854185×10−12kg−1m−3A2)
4. Numerical 4:- Two electrons occupying the same orbital are distinguished by:
5. Numerical 5:- An atom of an element contains 29 electrons and 35 neutrons.
Deduce (i) the number of protons and (ii) the electronic configuration of the element.
6.Numerical 6:- The energy of an electron in the nth Bohr orbit of H atom is –
7. Numerical 7:-The ground state energy of hydrogen atom is –13.6 eV. Consider an electronic state Ψ of He+ whose energy, azimuthal quantum number and magnetic quantum number are –3.4 eV, 2 and 0, respectively. Which of the following statement(s) is (are) true for the state Ψ?
8. Numerical 8:- The most probable radius (in pm) for finding the electron in He+ is
9. Numerical 9:- The atomic number of an element in 35. What is the total number of electrons present in all the p-orbitals of the ground state atom of the element?
10. Numerical 10:- An electron is in one of the 3d orbitals. Give the possible values of n, l and mI for this electron.
11. Numerical 11:- Which among the following species has the same number of electrons in its outermost as well as penultimate shell?
