Yes. Some of the larger units can create potential differences of several hundred thousand volts with ease, and the really big ones push several million volts. And they can do this with a good ability to deliver a big shot of current at that potential. A jolt from a Van de Graaf generator working in those ranges would be fatal.
Yes, negative ions can be accelerated using a Van de Graaff generator. The generator can produce a high voltage difference that accelerates the ions, regardless of their charge. The ions will be repelled or attracted according to their charge, gaining kinetic energy in the process.
A Van de Graaff generator creates static electricity by transferring excess electrons to the metal dome on top. When you touch the dome, the excess electrons flow into your body, causing your hair strands to repel each other due to the same charge, making them stand up.
The breakdown voltage of the insulating material surrounding the generator limits the potential difference it can achieve. This is the point at which the insulation breaks down and allows current to flow through, preventing further increase in potential difference. Additionally, spark discharges can occur if the potential difference exceeds a certain threshold.
When puffed rice is thrown onto a Van de Graaff generator, the grains will be attracted to the generator due to static electricity buildup. The grains may stick to the surface of the generator momentarily before being repelled as the charge redistributes.
When operating a Van de Graaff generator, it is important to follow safety precautions such as wearing rubber-soled shoes, avoiding contact with the generator while it is in operation, and ensuring that the generator is properly grounded to prevent electric shocks. Additionally, it is important to keep the generator away from water and flammable materials to prevent accidents.

You can build one for the cost of a motor, PVC pipe, rollers, belt, some wire and a couple stainless steel salad bowls...That could be around $30. See the link for one person's DIY Van de Graaf. You can buy one from Edmund Scientific for $500
Using a wooden sphere for the dome of a Van de Graaff generator is not advisable as wood is not a conductive material, which is necessary for the generator to function properly. A metal sphere or other conductive material would be more suitable for the dome of a Van de Graaff generator.
NO....a metallic dome must be used ,so that cahrges get accumulated on it...a wooden block(insulator) cannot do that..
Yes, negative ions can be accelerated using a Van de Graaff generator. The generator can produce a high voltage difference that accelerates the ions, regardless of their charge. The ions will be repelled or attracted according to their charge, gaining kinetic energy in the process.
The basic use of a Van de Graaf generator is to separate electric charges and build them up, frequently for demonstration purposes. A "big" version can be used to provide a burst of energy for generating X-rays, or for accelerating electrons or protons. The accelerated charges find some practical applications as well as some uses in scientific investigations. It's an electrostatic generator, and it will create a considerable difference of potential. Use the links below to read more about it and what we use it for.
"A Van de Graaff generator is an electrostatic machine which uses a moving belt to accumulate very high electrostatically stable voltages on a hollow metal globe. The potential differences achieved in modern Van de Graaff generators can reach 5 megavolts. The Van de Graaff generator can be thought of as a constant-current source connected in parallel with a capacitor and a very large electrical resistance."
