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 ...
Periodic trend The gradual change of any property in the elements across a period or down a group. Group An identifier used to describe the column of the standard periodic table. There are 18 groups in total on the periodic table Block A set of elements located in adjacent element groups. ...

The periodic trend in atomic radius depends on two factors: (1) principal quantum number and (2) effective nuclear charge. These two factors contrarily affect the atomic radius.Answer and Explanation: In the periodic table, the principal quantum number predominantly controls the ...

periodic trend for atomic radius Definition increases "right to left" and increases "top to bottom"; increases as you go southwest Term periodic trend for effective nuclear charge (Zeff) Definition increases "left to right" and increases "bottom to top"; increases as you go northeast Term ionic...
there's an explanation for this. As you move across a row of the periodic table, the ionic radius decreases for metals formingcations, as the metals lose their outer electron orbitals. The ionic radius increases for nonmetals as the effective nuclear charge decreases due to the number of elec...
