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.
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).
One kWh has 2.25 x 1025 eV. (The electron-volt is a very small unit, used in particle physics.)
Its mass remains the same (except for the very small amounts that stick to the knife blade).
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.
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).
No, the electron cloud is not heavy. An electron weighs approximately 2000 times less than a proton or a neutron, so almost all the weight of an atom lies in the nucleus, not in the electron cloud.
An electron has a very small mass, not a large mass.
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.
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
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.
Neutrinos, but their mass is very, very small.
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.
In the atom, protons and neutrons; the mass of the electron is very small.
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.
Scientists think that atoms basically look like an electron cloud circling a small, very dense nucleus. The electron cloud is negatively charged, makes up most of the volume of the atom, and has hardly any mass, but the nucleus is positively charged, very small, and contains all of the mass of the atom.
A electron is a subatomic particle outside the nucleus carrying a negative charge and very little mass. Other mass is negligible mass or a negative charge.
