Question

Statement 1: The angular nodes in a 2p-shell is one.
Statement 2: p-shell is dumb-bell shaped.

• A. Statement 1 is true, statement 2 is true; statement 2 is correct explanation for statement 1.
• B. Statement 1 is true, statement 2 is true; statement 2 is not a correct explanation for statement 1.

• D. Statement 1 is False, statement 2 is True.

Answer 1

The correct option is B Statement 1 is true, statement 2 is true; statement 2 is not a correct explanation for statement 1.

The angular nodes for an orbital is given by $l$.
For a p-orbital , $l=1$. Also, the shape of the orbital depends on the electron densities and the probability for finding an electron at a point.
