Homework Answers
Orbit & orbital are two different terms.
The concept of orbit was first introduced by Bohr. The electron in the atom revolves around the nucleus in a circular path of fixed radius and energy . These paths are called orbits. The orbits are nothing but the energy shells around the nucleus in atom.
Orbital is defined as, a region in the space around the nucleus where the probability of finding electron is maximum.
From above facts , the correct answer is option number 3.
An orbit is a fixed path at definite distance from the nucleus in which electron revolves around the nucleus. An orbital is region in the space around the nucleus where the probability of finding electron is maximum.

Consider an electron within the ls orbital of a hydrogen atom. The normalized probability of finding the electron within a sphere of a radius R centered at the nucleus is given by normalized probability = [az-e * (až + 2a, R+ 2R)] where a, is the Bohr radius. For a hydrogen atom, ao = 0.529 Å. What is the probability of finding an electron within one Bohr radius of the nucleus? normalized probability: 0.323 Why is the probability of finding...

Consider an electron in a 2s orbital of hydrogen (Z=1). Calculate the probability that the electron will be found anywhere in a shell formed by a region between a sphere of radius r and radius 1.0pm greater than the r value. Do this calculation in Excel for r from 1 to 600 pm in increments of 1pm. (You will be calculating the probability for successive shells at greater and greater distances from the nucleus.) Plot the resulting curve with probability...
