As down a group Trend: decreaseReason: The increasing of shielding effect by inner shells and the increasing of size of atom outweigh the increasing of proton numbers. So attraction between nucleus and outmost electrons becomes weaker and weaker and less energy is needed to remove the electron aw...
A: Ionization enthalpy decreases on moving down the group . R: Force of attraction between nucleus and electrons decreases on moving down the group. View Solution Ionisation energy increases on moving down a group in the periodic table.
What is ionization enthalpy ? On what factors does it depend ? How does ionisation enthapy of the elements very as we move down a group and along a period ? View Solution The tendency to exhibit−3oxidation state by a group VA element decreases down the group. Why ?
when we see the trend of ionisation enthalpy in the groups, it decreases from top to bottom in a group. this is because the number of shells increases down the group, due to which the outermost electrons will be far away from the nucleus and consequently, the effective nuclear charge is ...
