To account for the observation that the first ionization energy of the 5d series is higher than that of the 3d and 4d transition elements in their respective groups, we can break down the explanation into several key points: ### Step-by-Step Explanation: 1. **Understanding Ionization Energy**: - Ionization energy is the energy required to remove an electron from an atom in the gaseous state. Higher ionization energy indicates that it is more difficult to remove an electron. **Hint**: Remember that ionization energy increases across a period and decreases down a group in the periodic table. ...

Knowledge Check

  • First IE of 5d seties element are higher than those of 3d and 4d series elements. This is due to:

    A
    bigger size of atoms of `5d` -series elements than `3d` series elements
    B
    Greater effective nuclear charge is experienced by valence electrons because of the weak shielding of the nuclear by `4f`-electrons in `5d` series.
    C
    (A) and (B) both
    D
    None of these
  • Among 3d transition series the IE

    A
    Increases regularly in moving from left to right
    B
    Decrease regularly in moving from left to right
    C
    Remains constant within the period
    D
    increases gradually within the period but the relativ increase is not sharp.

    How would you account for the following? (i) The atomic radii of the metals of the third (5d) series of transition elements are virtually the same as those of the corresponding member of the second (4d) serie (ii) Because oxygen and fluorine are highly electronegative elements and small in size.
