Among 3d transition series the ionization enthalpy:
Decreases regularly on moving from left to right
Increases regularly on moving from left to right
Remains constant within the period
Increases gradually within period but relative increase is not sharp.
Among 3d transition series the I.E increases gradually within period but relative increase is not sharp.
The density of elements of 3d series across a period:
Explain the following (i) Electronegativity of elements increase on moving from left to right in the periodic table.
(ii) Ionisation enthalpy decreases in a group from top to bottom.
