down the group the tendency to loose electron increases as ionisation enthalpy decreases.
in a period from left to ryt the tendency to loose electron decreases as the size decreases
hope this helps u
if this helped u then send a smile

Hey mate...
=========
▪I think the tendency to lose electrons will change in a group !
Details:--
======
As we move down from one group to the next in our modern periodic table , the no. of shells present in an element increases. And this leads to a decrease in nuclear charge because as new shells are being added, electrons are getting more and more away from the nucleus and hence, the tendency to lose electron increases and the element becomes more electro-positive.
▪How will this tendency change in a period ?
Details:-
=======
When we go from one element to the next in a period , the atomic no. of the element increases and also, the atomic radius ( size ) changes due to an increase in nuclear charge which tends to pull the electrons closer to the nucleus and reduces the size of the atom. As the effective nuclear charge increases in a period, the tendency to lose electrons will decrease and hence, the element becomes more electro-negative in nature.
Hope it helps !! ☺
