Please tell me that node of p-orbital is at nucleus or no. plz give me right concept about orbital.
It doesn't work this way. You have to read about in your textbook and then come back if you don't understand something.
I always thought the p orbital had a node at the nucleus.
I thought every orbital had a node at the nucleus? Heisenberg?
Not s orbitals. A node is where the wave equation changes sign. When you have 1 node, you have at least 2 lobes.
