at 7:30 min nowhere is mention that S1 and S2 are of equal quantity
  1. Periodic Properties

  2. Lecture Plan Long form of Periodic Table Effective Nuclear Charge Atomic and lonic Radii

  3. Long form of Periodic Table . Periodicity

  4. Long form of Periodic Table . Periodicity

  5. Long form of Periodic Table "In the elements of first group, the outer most shell contain only one electron."

  6. Long form of Periodic Table Periodicity Periodic Law Periods-Seven Horizontal Rows Groups-Eighteen Vertical Columns Different blocks of Elements-s,p,d & f- blocks

  7. Long form of Periodic Table onour Periodic Table of weird Elements IA 10 2 Li Be Na Mg 40 45 46 47 51 Rb Sr YZr Nb Mo Tc Ru Rh Pd Ag Cd In Sn Sb Te Xe 8 79 La Ce Pr Nb Pm Sm Eu Gd Tb Dy Ho Er Tm Yb Lu 194 93 196 197 198 199 100 1011102 103

  8. Effective Nuclear Charge .Nuclear charge(Z) Shielding effect/Screening effect Shielding constant/Screening constant (S or ) Slater's Rule-Proposed by J C Slater in 1930

  9. Effective Nuclear Charge Effective nuclear charge (Zeff)-Z-o, It depends upon the penetration power of various orbitals. s>p>d> f

  10. Atomic and lonic Radi Atomic radii- distance from the centre of the nucleus to the outer most shell of electrons of atom/ion. Atomic radii can be covalent radii, ionic radii Vander Waal's radii etc. depending upon the nature of bond.
