Helium has a electronic configuration of 1 but it is placed in p-block in group 18. Explain. |
|
Answer» ctronic configuration of helium is but it is placed in GROUP 18 because it is a non-metallic GAS and its physical & chemical properties are similar to that of the group 18 elements. So, it is placed in p-block elements. These group elements are termed as NOBLE gases.They have a completely filled ELECTRONIC configuration and have zero valence electron.By possessing such a configuration, they tend to be highly stable. |
