Generally electrolytes' ions bind to the surface and damage the double electrostatic layer of colloidal particles. This greatly reduces stability of a colloidal system, since electrostatic repulsion is the main force keeping those colloidal particles apart.
Dispersed particles
the colloidal particle show tyndal effect while suspended particles donot. Colloidal particles donot settle down but the suspended particles get settledown.
A colloidal mixture contain particles with dimension under 1 000 nm.
The colloidal particles in a colloid form the dispersed phase, which is the smaller particles that are suspended within a continuous medium known as the dispersing medium.
Colloidal particles are typically filtered using techniques such as ultrafiltration or microfiltration, which involve passing the colloidal suspension through a porous membrane to separate the particles based on their size and charge. Other methods like centrifugation or flocculation can also be used to separate colloidal particles from a solution.

When particles are suspended in a viscous (thick) mixture. Lots of oatmeal based lotions are colloidal.
Colloidal particles in air can be harmful because they are suspended in the air and can easily be inhaled into the lungs, leading to respiratory issues. These particles, which often include pollutants and allergens, can also irritate the respiratory tract and exacerbate conditions like asthma or allergies. Additionally, some colloidal particles may contain toxic substances that can have adverse health effects when inhaled.
A dispersed colloidal particle can absorb electrically charged particles (either positive or negative) on its surface. Colloidal particles of a given kind will all have the same electric charge. Because of this , the dispersed colloidal particles repel each other.
Unfilterable clay particles can indeed form a colloidal solution. In a colloidal solution, particles are small enough (typically between 1 nanometer and 1 micron) to remain suspended and not settle out under the influence of gravity. The term "unfilterable" suggests that these particles are too small to be removed by standard filtration methods, which is characteristic of colloids. Therefore, unfilterable clay particles can be classified as part of a colloidal system.
If you are referring to any metal particles suspended in water I believe the term you are looking for is Colloidal. For example.... Colloidal Silver is silver particles suspended in water.
