Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.

(a) In a universe in which Planck’s constant had the value
h =1 J s, what would be the de Broglie wavelength of
a 145-g baseball moving at a speed of 20 m s-1 ?
(b) Suppose the speed of the ball from part (a) is known to lie between 19 and 21 m s-1
. What is the smallest distance within which it can be known to lie?
(c) Suppose that in this universe the mass of the electron is
1 g and the charge on the electron is 1 C. Calculate the Bohr radius of the hydrogen atom in this universe.
