Hi, here we have to answer some questions related to elements.
00:05
Now firstly, hydrogen can be placed in halogen family.
00:21
Now, hydrogen has one valence electron and it needs one electron to complete its duplet, that is, to achieve noble gas configuration of h .e.
00:50
Molecule atom.
00:53
So, that is helium.
00:55
Now, similarly with halogens, seven valence electrons are there, and they need one electron to complete octet of them, that is, to achieve noble gas configuration.
01:21
So, now, now, hydrogen and halogen both need one electron so they can be placed in one family.
01:33
Now secondly, ionization energy is the energy needed to remove the outermost electron from the neutral gaseous atom.
01:45
So now ionization energy is inversely proportional to the atomic radius or we can call it the size of the atom.
01:56
Now, as size increases, ionization energy decreases...
