Cloud condensation nuclei are solid particles around which cloud droplets form. Dust and salt are examples of particles that can become cloud condensation nuclei.
Water droplets need to condense on them.

It's called a cloud chamber :)
A cloud is a form of gas it is made of small particles which are quite far apart you can turn liquids into gasses buy heating them (condensation)
Water droplets need to condense on them.
Clouds form when the water vapor condenses into small particles. The particles in clouds can either be liquid or solids. The liquid particles are called cloud droplets and the solid particles are called ice crystals! Both droplets and ice crystals require a solid particle to nucleate on - otherwise the moisture stays in the air in a supersaturated condition until something drastic happens to cause it to precipitate.
Liquid and solid. Clouds are formed from tiny droplets of water or ice. Low fluffy clouds are liquid, the high streak clouds are usually solid ice particles. You can see the droplets often when you walk through fog, which is the same as a cloud, but at ground level.
An aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas.
Conditions inside a cloud are not static: water droplets are constantly forming and re-evaporating. Most water droplets are formed when water vapor condenses around a condensation nucleus, a tiny particle of smoke, dust, ash or salt. In supersaturated conditions, water droplets may act as condensation nuclei.

You may be thinking about the term nucleation or coalescence. Creation of liquid droplets around aerosol particles is called nucleation. The aerosol particles themselves are known as seeds, while the water that form around them are known as droplets. When referring specifically to cloud formation in the atmosphere, the nucleation process is known as coalescence and the seeds can be called cloud condensation nuclei.These seeds can be natural, as in smaller water/ice particles or synthetic chemicals used for cloud seeding, including silver iodide and dry ice.
Cloud 'seeding' creates microscopic particles around which water droplets can form. The droplets 'stick' together to form raindrops. It's the addition of the 'foreign matter' that allows water to condense into rain.
"Condensation nuclei" are particles of dust around which a vapor can condense. This term is typically applied to water vapor condensing into raindrops, which then fall from the clouds.
