The density around a partial positive is typically less than the density around a partial negative. This is due to the ionization of the ion.
When two atoms come together and form a bond, they can do so by either sharing electrons or by taking/donating them. When they share electrons, electron density is smeared out between the atoms. (You can think about an electron bouncing back and fourth between the atoms.) When an ionic bond forms, one atom gives up one electron to another. When an atom gives up an electron, it becomes positive, and when an atom gains an electron it becomes negative. When this happens, you end up with one positive atom and one negative atom. Just like when opposite ends of a magnet attract one another, so do the positive and negative atoms. These opposites attract and stick together.
A dipole in a molecule occurs when there is an unequal distribution of electron density, leading to a separation of charge and the molecule having a positive and negative end. This can result in a molecule having a partial positive and partial negative charge, creating a polar molecule.
A molecule is polar if it has an uneven distribution of electron density, leading to a separation of positive and negative charges. In the case of CO, the oxygen atom is more electronegative than the carbon atom, pulling the shared electrons towards itself and creating a slight negative charge on the oxygen and a slight positive charge on the carbon.
electron cloud density is a criteria for suggesting availability of electrons in that area.
why do silicate materials have low electron density
Proton mass = approx. 1,850 x electron mass.If volumes are similar, then proton density = approx. 1,850 x electron density.

I believe the Nucleus of an Atom is positively charged with a very high density.
Electron density is the measure of the probability of an electron being present at a specific location. In molecules, regions of electron density are usually found around the atom, and its bonds.
The density of an electron is its mass divided by its volume. The rest mass of an electron is approximately 9x10-31 kg. The size, however, is much more difficult to determine as an electron is not a rigid ball - instead it is more like a wave, with diffuse edges. An approximate accepted size for an electron is 5 × 10-13 m, giving a it volume of 5x10-37m3. These figures give a density for the electron of approximately 1700 tonnes/m3, a density that is 154 times that of lead
Water is polar because of its bent shape (due to two lone pairs of electrons on the oxygen atom) and difference in electronegativity between oxygen and hydrogen atoms. This causes a slight negative charge on the oxygen atom and slight positive charges on the hydrogen atoms, creating a dipole moment in the molecule.
The idea is to divice the mass by the volume, to get the density. Then compare to the density of silver.The idea is to divice the mass by the volume, to get the density.

electron cloud density is a criteria for suggesting availability of electrons in that area.
It is called the electron cloud, the volume in which electrons are most likely to be found. This area is given by Schrodinger's wave equation, which defines psi, the wave function, which squared (psi2) is the probability density. Thus, high probability density equates high electron density. so get over it!
Due to the difference in the electronegativities of the bonded atoms, the more electronegative atom attracts the shared pair of electrons towards itself, which increases the negative charge density around the attracting atom, consequently the other atom has less negative charge density and thus a positive charge density (relatively positive) gets generated at the donor atom.
The region of zero electron density is called a "node."
