Does the questioner mean, "Why does the helium spectrum have more VISIBLE lines than hydrogen?"? I am not sure how many lines (within as well as outside the visible spectrum) that there are in the spectrum of each of these elements. I don't think anybody has worked out the spectrum of helium from first principles though they have for hydrogen (find out about the Balmer and Lyman series). To hazard a guess, I would think that, because helium has two electrons instead of hydrogen's one, there are many more energy levels they can have so the lines relating to each change of energy would be more bunched together, hence the greater the chance of them falling within the visible range.
The noble gases are all non-reactive. That would be helium, neon, argon, krypton, xenon and radon. I've worked with argon in glove boxes, so I know that it is available in compressed gas canisters.
Walt Disney worked at various animation studios before eventually founding his own, The Walt Disney Company. He started his career at the Kansas City Film Ad Company and later founded Laugh-O-Gram Studio, which eventually led to the creation of Disney Brothers Studio and then The Walt Disney Company.
because of gas in active center Neon gas worked as Active Center for He-Ne laser.to accelerate the Ne atoms very high and efficient Pumping is required. Which can only be given by Electric Discharge Pumping.
Bohr's theory for the hydrogen atom was initially accepted because it successfully explained the discrete line spectra observed in hydrogen. However, it was ultimately discarded because it couldn't fully explain the spectral lines of atoms with more than one electron, leading to the development of more comprehensive quantum mechanical models like wave mechanics.
A Zeppelin, or rigid airship works by using a large volume of gas that is lighter than air to help lift it off the ground. Just like a helium party balloon, Zeppelins were filled with hydrogen or helium and this would compensate for almost all of their weight. Zeppelins could lift many tons at a time when airplanes could barely lift themselves. Zeppelins formed the first airline (DELAG) in Germany and transported thousands of people. Zeppelins were different than blimps. They had rigid metal or wood frames inside that allowed large engines and passenger compartments to be outfitted. They didn't just have a tiny gondola underneath,m but had a great deal of living space inside the actual cigar shape. Zeppelins worked very well, and were considered very reliable. The problem was that the best airships (Zeppelins) were made in pre-WW2 Germany. They were filled with hydrogen, which is very flammable. Germany wanted to use helium (non-flammable), but the USA has a virtual monopoly on Helium production at that time, and it was considered a precious commodity that might be misused by Hitler in the event of a war. The eruption of the Hindenburg in Lakehurst New Jersey spelled the end for Zeppelins. People thought they were dangerous. In reality, had helium been used instead of hydrogen, we might still be using them today.
Yes, you can make a balloon fly using propellers or an electric motor to provide thrust. By attaching a propeller or motor to the balloon, you can create lift and propulsion to make it fly without the need for hot air or helium.
No, I have never received a W2 from a company that I never worked for.
That sentence is incorrect. It could be changed to,He is employed by a company, or He worked for a company, which are sentences having the same general idea.
The Hindenburg was a giant balloon airship filled with hydrogen gas for buoyancy.Hydrogen is the lightest of all gasses and has a mass of only half the mass of helium gas, so it worked well to lift the mass of the airship. The Hindenburg disaster took place on Thursday, May 6, 1937, and part of the disaster was due to the hydrogen gas catching fire. Helium would not catch fire since it is an inert gas.
No, I have never received a W2 form from a company where I have never worked before.
