Describe The Ways In Which Hydrogen And Explain Why It Exists

Helium is the second most abundant element in the universe, after hydrogen; however, it is rare on earth, primarily found mixed with natural gas trapped in underground pockets. Once helium is released it is so light it escapes the earth's atmosphere and cannot be recovered. At sea level, helium occurs in the atmosphere in the proportion of 5.4 parts per million. The proportion increases slightly at higher altitudes. About 1 part per million of atmospheric helium consists of helium-3, now thought to be a product of the decay of tritium, a radioactive hydrogen isotope of mass 3. The common helium isotope, helium-4, probably comes from radioactive alpha emitters in rocks. Natural gas, which contains an average of 0.4 percent helium, is the major commercial source of helium. By far the largest users of helium are agencies of the United States government.

The main point of lecture was to continue discussing about the light spectra and atoms. Specifically, we used the equations and calculated a photon of light’s energy at a certain wavelength. Also, we discussed the light spectrum and how particular wavelengths of light are absorbed by matter.

Experiments 2-1 and 2-2 study the production of hydrogen gas by different chemical reactions. By using a hydrogen gas collection apparatus and the principles of chemistry, we were able to evaluate the data and reach our goal. Experiment 2-1 uses zinc, magnesium and aluminum and how much hydrogen gas they produce to predict the volume of hydrogen gas produced for different masses of each metal. In this experiment we see that each metal has an increasing amount of hydrogen gas as mass goes up, however each metal had different amount of hydrogen gas for the same mass. Zinc produced the least amount of hydrogen gas, then increasing with magnesium, and aluminum produced the highest amount. The

Helium is a lighter than air gas. It has a 4.00260 atomic mass while air or oxygen has a 15.9994 atomic mass . According to Jefferson Lab editor Thomas Jefferson National Accelerator Facility “Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth.” (2017,[online]). Oxygen is one of the most common gas and every living thing needs it to live. “Oxygen is written as

When hydrogen is viewed through a spectroscope, a red line appears on the line spectrum. In a line spectrum, the spectrum of an element appears not a band of color, but as a sequence of lines.

When the atoms return to their ground state, they give off a color. This color is produced by the photons emitted; it has a specific amount of energy because all of the elements have a collection of different emission spectra because they all have a different amount of electrons in their energy sublevels. The energy absorbed and released has to be the same amount or it will not produce color. Only when both are equal, will a wavelength be given

During the Atomic line emission lab assignment, my results came out pretty accurate. During the 5th lab it was very fatiguing to determine what the colors were that I had seen. Basically there was a large amount of red. As I went down the line there was a decrease of the rest of the colors, meaning there was more of the red than any other color. As a group we realized this lab emission was a lot like Ge or Germanium based on the spectrum. The first Lab we saw that it was a lot similar to Ce which was Cerium, it is very common to Germanium. With both labs five and 1, you had all the colors except there was no green or violet. Ge had every color except for violet. Our eyes are sensitive to different wavelengths of visible light and we see these

Usually an excited state can take the form of the electron bouncing from its start energy level or annual also called the ground state. The excited states that are found in the atoms which are in molecules are really crucial for some chemical reactions. The excited electron does not stay in the excited state for a long time, in a while it goes down back to the ground state. When an electron goes down from the excited state, its energy decreases in the form of light, this process is called emission (What is an Excited

Solids and liquids glow at very high temperatures. To see these glow, you need to look at using a spectroscope. When you do look through the spectroscope, you see a band of colors that resembles a rainbow. The reason why this happens is because the atoms are packed closely together. In the early 1900’s, Niels Henrik David Bohr created an explanation why the lines of the spectrum are the way they are. Niels Bohr was a Danish born physicist who is world renowned for his works of quantum physics. Bohr proposed that electron that orbits the cloud of protons and neutrons has a set to have a certain energy. When the electron occupies the energy level of lowest energy, it is in its ground state. If an electron occupies a higher energy levels then

Helium makes up about Helium is the second most abundant element in the universe. It was discovered on the sun before it was found on earth. In 1868 a french astronomer, Pierre-Jules-Cesar Janssen noticed a yellow line in the sun’s spectrum while studying a total solar eclipse. With a wavelength of 587.49 nanometers Norman Lockyer realized that this line could not be produced by any element at the time. It was hypothesized that the sun was responsible for this mysterious yellow emission. Lockyer named the unknown element helium.

Emission spectra is referred to as the “fingerprint of the elements” because each element has a different pattern of emission or absorption lines that is detected in a spectrum.

Within the data, it is to be noted that widely across different elements, the amount of frequency and wavelength are similar to colors diverse from the one’s element. The energy for Neon at blue was, 4.23×10-19J, and the energy of Argon was 4.42×10-19J. Wavelengths with similar wavelengths have equal to or close to the same amount of energy and or frequency. Within this lab, there was equipment failure with the spectrometers. Most of the data collected in terms of wavelength was attributed to a diagram stating the correct wavelength for a given element’s color. The spectrometers were proven to be an ineffective way to measure the wavelength of the atoms of a given element because multiple lab groups had the same error in their observations.

Helium, a noble gas, is the second most abundant element in the universe. It was discovered on the sun before it was found on earth by French astronomer Pierre-Jules-Cesar Janssen in 1868. Helium received its name from the Greek word for sun, helios. Even though helium is so abundant throughout the universe it is relatively rare on Earth.

Comparing the hydrogen to lithium, hydrogen is an element with little orbitals compared to lithium. Hydrogen has little amounts of energy levels, so its energy is diagram will

Solar telescopes are able to take detailed photos of the sun, as they only allow specific wavelengths. This wavelength is otherwise known as hydrogen alpha (656.281 nm) which marks the transition of electrons around the hydrogen atom, from the third leveled to the second leveled. Using the Bohr model of the hydrogen atom, the transition of an electron from n=3 to n-2, releases a fixed amount of energy which radiates at that specific wavelengths. This allows us the see into the chromosphere of the sun. According to the Bohr model of the atom, electrons exist in quantitative energy levels surrounding the atom's nucleus.
