Question

List - I	List - II
A) Nodal plane	1) $\frac{Z{e}^2}{2r}$
B) p-orbital	2) $\lambda =\frac{h}{mv}$
C) de Broglie	3) Spherical
D) The kinetic energy of an electron	4) Probability of finding an electron is zero
	5) Dumb bell

The correct match is:

• A. A-4, B-5, C-2, D-1.
• B. A-2, B-4, C-3, D-5.
• C. A-1, B-5, C-3, D-2.
• D. A-3, B-1, C-4, D-2.

Answer 1

The correct option is A A-4, B-5, C-2, D-1.

The plane in which probability of finding an electron is zero is called nodal plane.

Shape of p-orbital is Dumb bell.

de Broglie's equation for wave-particle duality is: $\lambda =\frac{h}{mv}$.

The kinetic energy of an electron is given by $\frac{Z{e}^2}{2r}$.

Hence option (A) is correct.
