Why does the helium spectrum have more lines than the hydrogen spectrum?
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.
Why was Bohr's theory for the hydrogen atom initially accepted and why was it ultimately discarded?
Because it worked perfectly for the hydrogen atom, but not for any other element.
What gas does not liquefy?
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.
Why electrical discharge pumping is used in helium neon laser?
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.
Who invented fibre optics?
Optical fibre was invented in 1966 by two British scientists, Charles Kao and George Hockham. They worked for the British company Standard Telecommunication.
Can you make a balloon fly without hot air or helium?
Yes: Try hydrogen - it worked for the Hindenburg
How did hydrogen make the Hindenburg rise?
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.
How did the zeppelin blow up?
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.
Who recognised that large energy is released as a result of the fusion of hydrogen nuclei to form deuterium?
The most likely fusion reaction to be exploited is deuterium + tritium forming helium +a neutron, not what you have put in your question. The physics of this was worked out by Hans Bethe
He is worked to a company. Is it write sentence?
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.

What team of scientists worked for the first time on the research of the Hydrogen Bomb?
The team of scientists that worked for the first time on the research of the Hydrogen Bomb would be the Aldermaston scientists. Sir William Penney was in charge of the project.

What are the starting materials for a star?
A star is mainly up of hydrogen, and a little bit of helium. When those two clump together, they begin to have an enormous amount of gravity, pulling the hydrogen atoms close to the center of the star. The gathering of all these atoms in one place contributed to a very high temperature, and so much collision might allow two hydrogen atoms to form one helium atoms in a process called " Nuclear Fusion". Nuclear releases a lot of electrons into space (energy released), and these " shooting electrons" is what makes the star shine.

Who did Simon Fraser work for?
he worked for the northwest company.
