A particle of matter is moving with a kinetic energy of 8.15 eV. Its de Broglie wavelength is 2.34 x 10^-12 m. What is the mass of the particle? 3.07E-26 kg 1.84E-26 kg 3.68E-26 kg 5.22E-26 kg
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.

The kinetic energy of the particle is given by,
where K = kinetic energy in J
m = mass in Kg
And v = velocity in m/s
The de Broglie wavelength of any specie is given by,
where h = Plank's constant = 6.626 X 10-34 Js
λ = de Broglie wavelength in m = 2.34 X 10-12 m
And p = momentum of specie in Kg.m/s
Since p = mv
where m = mass in Kg
And v = velocity in m/s
