  6. MY TUSION CLASSIC

  7. 1 ELECTRONIC CONFIGURATION • Actinide element is [Rn] 5f^0-14 6d^0-2 7s^2 [Rn]=Redon=83 • In actinide element has first element is Actinum Atomic No is 89 and last element is Lawrencium Atomic No is 103 • Electronic configuration are as under

  8. Sr.No Atomic no Name Symbol Ele.con. • 1 89 Actinium Ac [Rn] • 2 90 ThoriamTh [Rn] • 3 91 Protactinum Pa [Rn] • 4 92 Uranium U [Rn] • 5 93 Neptunium Np [Rn] • 6 94 Plutonium Pu [Rn]

  9. 7 95 Americium Am [Rn] • 8 96 Curium Cm [Rn] • 9 97 Berkelium Bk [Rn] • 10 98 Californium Cf [Rn] • 11 99 Einstenium Es [Rn] • 12 100 Fermium Fm [Rn] • 13 101 Mendelevium Md [Rn] • 14 102 Nobelium No [Rn] • 15 103 LawerenciumLr [Rn]

  10. 2 0xidation State • The Known oxidatino state of the element we shown as under • Element Ato.No Oxidation state • Ac 89 +3_ • Th 90 +2 (+3) +4_ • Pa 91 (+3) +4 +5_ • U 92 +3 +4 +5 +6 • Np 93 +3 +4 +5_ +6 +7 • Pu 94 +3 +4_ +5 +6 +7 • Am 95 +2 +3_ (+4) +5 +6

  11. Cm 96 +3_ (+4) • Bk 97 +3 +4_ • Cf 98 (+2) +3_ • Es 99 (+2) +3_ • Fm 100 (+2) +3_ • Md 101 (+2) +3 • No 102 +2 +3_ • Lr 103 +3_

  12. +2 Oxidation state : • State in some compounds like ThBr2,ThI2,ThS , ete . • Am +2 Oxidation state is unstable • 5f^7 half contrigation

  13. +3 Oxidation state : • Th and Pa all other actinide element shown +3 oxidation state . • The +3 oxidation state is more stable state • Ac,Am and element following Am • U +3 ion is easily in +4 oxidation

  14. +4 Oxidation state : • +4 oxidation stateis prime oxidation state for the • Th element +4 oxidation state is present in Pa,U,Np & Bk • +4 oxidation state element acidic solution are precipated as a Iodate,oxalate ,phosphate & fluoride

  15. +5 Oxidation state : • Thisoxidation state is more stable for Pa,U,Pu & Am element • The order stability of MO2 ion is Np>Am>Pu>U • Which is obtained by the following reaction

  16. +6 Oxidation state : • This oxidation state the simple compounds of hexa fluoride of U,Np & Pu are formed (MF6) in this state U,Np,Pu & Am are form mainly dioxoiions (MO2) • According to that the order of stability of MO2 is U>Pu>Np>Am obtained MO2ions are very stable • AmO2 ion very earily reduce

  17. +7 Oxidation state : • Thisstateis only persouted by Oxo Negative ions of Np and Pu • They are obtained by the Oxidation of alkaline solution with Ozone (O3) by heating of puo2 and Lio2 in Oxygen • These Oxo negation ions are as follons NpO2(OH)2 and P4O6
