What is the shape of 1s and `2s` orbital .Give two point of difference between `1s` and `2s` orbital

Text Solution

Verified by Experts

The correct Answer is:
s-orbital: Shapr rarr spherical
`(##RES_PHY_CHM_V01_XI_C02_E01_023_A01##)`
Size of `2s` is more then `1s` and `2s` contain `1` radial node while `1s` does not.
