Question

name the elements whuch has lowest
1. ionisation enthalpy
2. melting point

Answer 1

Hii There!!


1) Cs ( Cesium ) has the lowest ionization enthalpy.
As we know that, in periodic table from top to bottom size increases and due to that the ability of an element to remove an electron in gaseous state of an atom is increased.


2) Helium is the element having the lowest melting point . In an ionic compound they having high melting point and boiling point becoz, of strong ionic bond.

I hope it's clear to you ☺️
