24.Choose the correct statements from the following - A) A node is a point in space where the wave function ( `Psi` ) has zero amplitude B) Total number of nodes in an orbital is equal to (n-1) C) `Psi^(2)` represents the probability density of finding the electron D) Total no.of angular node in `2p_(x)` orbital is one

Assertion : 2s-orbital has one node. Reason : Number of nodes in an orbital is equal to (n - l -1) value.

A : the number of angular nodes in 3d _(z^2) is zero R : Number of angular nodes of atomic orbitals is equal to value of l.

Orbitals are the pictorial representationof Psi or Psi ^(2) Psi^(2) tell about the probability of finding electron. Which of the following graph is correct for 3p ?

Orbitals are the pictorial representationof Psi or Psi ^(2) Psi^(2) tell about the probability of finding electron. A 2p_(x) orbital is shown by given diagram Correct regarding diagram is

Choose the incorrect statement among the following a) Psi^(2) represents the atomic orbital b) The number of peaks in radial distribution is "n-1 c) A node is a point in space around nucleus where the wave function Psi becomes maximum value d) The number of angular nodes for S orbital is zero

Select the correct statements for hydrogen like atoms or ions. (A) Radius of an orbit is inversely proportional to Z (B) Radius of an orbit is directly proportional Z^2 (C) Total energy of the electron in an orbit is inversely proportional to Z (D) Magnitude of total energy of the electron in an orbit is directly proportional to Z^(2)

The Schrodinger wave equation for H-atom is nabla^(2) Psi = (8pi^(2)m)/(h^(2)) (E-V) Psi = 0 Where nabla^(2) = (del^(2))/(delx^(2)) +(del^(2))/(dely^(2)) +(del^(2))/(delz^(2)) E = Total energy and V=potential energy wave function Psi_(((r, theta,phi)))R_((r))Theta_((theta))Phi_((phi)) R is radial wave function which is function of ''r'' only, where r is the distance from nucleus. Theta and Phi are angular wave function. R^(2) is known as radial probability density and 4pir^(2)R^(2)dr is known as radial probability function i.e., the probability of finding the electron is spherical shell of thickness dr. Number of radial node =n -l - 1 Number of angular node = l For hydrogen atom, wave function for 1s and 2s-orbitals are: Psi_(1s) = sqrt((1)/(pia_(0)^(a)))e^(-z_(r)//a_(0)) Psi_(2s) = ((Z)/(2a_(0)))^(½) (1-(Zr)/(a_(0)))e^(-(Zr)/(a_(0))) The plot of radial probability function 4pir^(2)R^(2) aganist r will be: Answer the following questions: The following graph is plotted for ns-orbitals The value of 'n' will be:
