The electron cloud has such a small mass because that's where all the electrons are! Electrons are fundamental particles having a mass of only 9.109 X 10-31 kg. To put that into perspective, a proton has a mass of over 1,800 times that of the electron.

What is the best example of the purpose of scientific notation?
Any number that is very large, or very small (near zero). For example, the mass of the Sun in kilograms (large), the distance to the M31 galaxy in meters (large), or the mass of the electron in kilograms (small).
How many electron volts per kilowatt hour?
One kWh has 2.25 x 1025 eV. (The electron-volt is a very small unit, used in particle physics.)
When you cut an apple into pieces does its mass stay the same or does it get smaller?
Its mass remains the same (except for the very small amounts that stick to the knife blade).
Does the period of simple pendulum depend on the mass of the bob?
Not in the theoretical world, in the practical world: just a very little. The period is determined primarily by the length of the pendulum. If the rod is not a very small fraction of the mass of the bob then the mass center of the rod will have to be taken into account when calculating the "length" of the pendulum.
What are defects of e equals mc2?
The formula E=mc2 states that the conversion ratio of mass to energy is "Energy=mass times the speed of light squared" (which indicates that the conversion of a small amount of mass can create a very large amount of energy).
Is the electron cloud heavy?
The electron cloud, which consists of electrons orbiting the nucleus of an atom, is extremely light. The mass of an electron is about 1/1836 times the mass of a proton, so the electron cloud contributes very little to the overall mass of an atom.
Does an electron have a large or small mass?
An electron has a very small mass compared to larger particles like protons and neutrons. Its mass is approximately 1/1836 times the mass of a proton.
Which is more dense the nucleus or the electron cloud?
The nucleus is significantly more dense than the electron cloud. The nucleus contains most of the mass of an atom, while the electron cloud occupies a much larger volume with a very low density.
Does a atom gain mass during ionization?
When an element loses an electron(s) to form a cation there is a very very small decrease in mass When an anion is formed by gaining electron(s) there is a very small increase. A proton weighs roughly the same as a neutron and these are nearly 2000X the mass of an electron.
What will be the effect of the removal of an electron to the mass of atom?
As mass of elactron is very small as compare to proton and neutron So there will be no effect on mass if electron is removed
What particles the one with the least mass is the electron proton neutron or neutrino?
Neutrinos, but their mass is very, very small.
Does a electron have almost no mass?
An electron has a very small mass compared to other particles, such as protons and neutrons. Its mass is about 1/1836 of the mass of a proton or neutron.
What are the two subatomic particles with a mass?
In the atom, protons and neutrons; the mass of the electron is very small.
What unit is designated by amu?
The unit designated by amu stands for atomic mass unit. It is used to express the mass of atoms and molecules on a very small scale, equivalent to one twelfth of the mass of a carbon-12 atom.
What is todays atom model?
The modern atom model is based on quantum mechanics and describes the atom as having a nucleus containing protons and neutrons, surrounded by electrons in orbitals. This model emphasizes the probabilistic nature of electron distribution rather than fixed orbits.
Elementary particle that carries a negative charge and almost no mass?
An electron is an elementary particle that carries a negative charge and has a very small mass.
Why are electrons not used to determine the mass number or atomic mass of atoms?
because
