What is the eigenfunction for the 1s orbital of H atom?
The wave function for 1s orbital of the hydrogen atom is given by. Ψ1s=2 πe−r/a0. where a0= Radius of first Bohr orbit. r= Distance from the nucleus (Probability of finding the electron varies with respect to it)
What is the wave function of hydrogen atom?
The hydrogen-atom wave function for n = 1, 2, and 3 are given below. The constant a0 appearing in these functions has the value a0 = 52.92 pm. The probability of finding the electron in a small volume ∆V about the point (r,θ,φ) is |ψnlm(r,θ,φ)|2∆V….

What is the orbit time of 1s electron in hydrogen?
and v = 2.165 x 106 x Z/n, For hydrogen atom, Z = 1. Therefore, That is, the orbit period of electron is 2.46 × 10–15 s.
Why the wave function for electron in hydrogen atom should approach zero as R → 0 and r → ∞?
Radial wavefunctions The exponential factor is always positive, so the nodes and sign of R(r) depends on the behavior of p(r). Because the exponential factor has a negative sign in the exponent, R(r) will approach 0 as r goes to infinity.
What is difference between radial and angular wave function?
Radial wave functions for a given atom depend only upon the distance, r from the nucleus. Angular wave functions depend only upon direction, and, in effect, describe the shape of an orbital.
What is Schrödinger’s equation of the hydrogen atom?
As a result, Schrödinger’s equation of the hydrogen atom reduces to two simpler equations: one that depends only on space ( x, y, z) and another that depends only on time ( t ). (The separation of a wave function into space- and time-dependent parts for time-independent potential energy functions is discussed in Quantum Mechanics .)
What is the quantum model of a hydrogen atom?
A hydrogen atom can be described in terms of its wave function, probability density, total energy, and orbital angular momentum. The state of an electron in a hydrogen atom is specified by its quantum numbers (n, l, m). In contrast to the Bohr model of the atom, the Schrödinger model makes predictions based on probability statements.
What is the total wave function of an electron?
where is the three-dimensional wave function of the electron, is the mass of the electron, and E is the total energy of the electron. Recall that the total wave function is the product of the space-dependent wave function and the time-dependent wave function .
What are the three quantum numbers of the hydrogen atom?
Each of the three quantum numbers of the hydrogen atom ( n, l, m) is associated with a different physical quantity. The principal quantum number n is associated with the total energy of the electron, .
