One of the most important properties of colloidal solutions is that colloidal particles posses a definite type of electrical charge. In a particular colloidal solution, all the colloidal particles carry the same type of charge, while the dispersion medium has an equal but opposite charge. Thus, the charge on colloidal particles is balanced by that of the dispersion medium and the colloidal solution as a whole is electrically neutral.

Are colloids homogenous?
Colloids are very small particles of a substance suspended in a mixture making them homogeneous.
The attraction of opposite electrical charges plays a role in?
The attraction of opposite electrical charges play a role in ionic bonds.
How do forces between between electrical charges differ from forces between masses?
Gravitational forces are always attractive. Electrical charges are repulsive for same-type charges, and attractive for opposite-types.
How do electric charges interact?
they move through electrical circits
What object is not an electrically neutral?
A object without electrical charges.
A flow of electrical charges is known as an?
A flow of electrical charges running through a medium is known as an electrical current.
Are colloids homogenous?
Colloids are very small particles of a substance suspended in a mixture making them homogeneous.
Electrical charges flow in the same path?
Electrical charges will not flow. The considered to be held stationary.
What is the different kind of ions?
Those with positive electrical charges, and those with negative electrical charges.
How is an electrical current related to the motion of charges on an atomic scale?
For most practical purposes, the electrical current IS the motion of charges. To be precise, it is the AVERAGE motion of charges per second; that is, there are also random movements to and fro, that are usually not considered when talking about the current.
What are the three types of electrical charges?
positivenegativeneutralCommentWithout wishing to be picky, 'neutral' is not a type of charge -it is a lack of charge.
Electric current is defined as what?
Electric current is defined as the movement of electrical charges.
The energy of moving electrical charges?
Electrical energy
Are colloids heterogeneous or homogeneous?
Colloids are stuck between heterogeneous and homogeneous mixture. So you can't say that it is a heterogeneous or homogeneous. It is both.
The form of energy carried by moving electrical charges is?
Electrical
What is the energy produced by electrical charges called?
electrical energy
The attraction of opposite electrical charges plays a role in?
The attraction of opposite electrical charges play a role in ionic bonds.
