Hydrogen: A Utile Element Essay

The elements were organized by Dimitri Mendeleév. He organized them by properties (columns), groups (horizontal), and atomic number (the number of protons and electrons). This became known as the Periodic Table. And currently there are 118 elements. He also found gaps in which elements that were yet to be discovered were to go, three of these unknown elements were found and identified in Mendeleév's lifetime. The elements today are used in everything and 75% of the 118 elements are metal.

According to Carolyn Ruth, author of “Where Do Chemical Elements Come From,” chemical elements came from the explosion of stars, also known as supernovas. In her article, Carolyn states that a newborn star is mainly composed of the first element on the periodic table, Hydrogen. Due to the high pressure within the star, a fusion process begins that fuses two protons and two neutrons together to form the second element, Helium. These fusion processes continue to form elements that weigh less than Iron. Once the star creates all elements up to Iron, the star eventually collapses and explodes. One article that agrees with Carolyn’s theory is “The Origin of the Elements and the Life of A Star”. According to this article, stars produce nuclear reactions

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

What is an atom? An atom is the basic building block of everything. An atom is made of electrons protons and neutrons and the number of protons determines the element. Back in the 1800’s this whole idea was unknown. In the 1800’s steam was starting to power everything. It became important to know how steam works, so you can learn to use it more effectively. It was this idea that drove Dalton to research the atom.

However, some pundits are concerned that adopting hydrogen energy as the sole strategy for the issues facing the automobile’s future is problematic because of the lengthy time frame in which they are projected to become ubiquitous. Furthermore, the present infrastructure for the distribution of hydrogen fuel sources or the production of hydrogen fuel cells is not only insufficient, but slow to develop. As such, fossil fuels are presently the main source for hydrogen production, which means that hydrogen vehicles do not successfully decouple the automobile from a fossil fuel economy. This is also widely inefficient because it will generate four times the carbon dioxide emissions generated by gasoline efficient automobiles. Furthermore, compressing hydrogen for the purposes of

Hydrogen was first found in later 16th century but it was not confirmed as a kind of chemical element by Henry Cavendish before 1766. It is a chemical element with symbol H and atomic number 1. That means it is the first one on the periodic table and each atom just has one proton and one electron.And with a standard atomic weight of 1.008, hydrogen is the lightest element on the periodic table. In addition ,it is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. On Earth,most of hydrogen exists in molecular forms such as water or organic compounds

Though there are over a hundred different elements, each one is unique in its complexity and properties. Helium has an atomic Number of two, that’s how you can tell it it has two positively charged atoms, or ‘protons’, in

Currently, hydrogen is generated from fossil fuels by the steam reforming of methane or natural gas. At extremely high temperatures from between 700-1100℃, steam water reacts with methane in an endothermic reaction to yield syngas (synthesis gas), which is a fuel gas mixture consisting primarily of hydrogen and carbon monoxide.

The purpose of this lab was to observe and reserve the emission spectra of various elements in which hydrogen was the element that was emphasized on. More specifically, the frequency, initial energy level, and change in energy of the element hydrogen was determined by the wavelength of the light in the hydrogen atom.

Hydrogen is the lightest and most abundant element on the periodic table and in the universe. Hydrogen has a boiling point of 20.28 K, and it is most commonly known as a gas on Earth. Further out in the galaxy, however, hydrogen is not restricted to the forms found on Earth.

The search for a renewable energy source has been a top priority to us a human race in the past decade. Many ideas have come in the form of wind, solar, and nuclear power, all having their own drawbacks. But, the one that will be focused upon in this analysis is hydrogen as a source of fuel, and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us, how it might hurt us, and whether it is worth pursuing from an ethical stance.

Hydrogen-3 is the only radioactive isotope of hydrogen. Tritium was first discovered, unintentionally, in 1934 by Physicist Ernest Rutherford, M.L. Oliphant and Paul Harteck. It was unintentional, as they had not expected tritium to be made by a mixture of deuterium and high-energy deuterons. Deuterons are the nuclei of deuterium atoms, and deuterium is the second isotope of hydrogen. Unfortunately, Rutherford was unable to isolate the matter and the position was later passed onto to Luis Alvarez and Robert Cornog. Hydrogen-3, can either be artificially or naturally made, however it is very rare to be made naturally. Since 1934, approximately 220 kilograms of tritium has been produced only, in the United States of America, however due to the

For the past three decades Oil dominates the agenda of political discussion. With scares over price volatility, sizes of reserves, international imports and least of which are the environmental impacts due to carbon dioxide and other emissions. Various speculations and educated guesses place our total depletion of crude oil within the next 50 years and there is a general consensus between environmentalists that we steer toward a hydrogen transportation system given the projected work and nonexistent carbon dioxide emissions (Environmental Technologies class lecture, Santa Clara University). However many barriers stand in the way of attaining such a goal, most of which pertaining

In order to understand the why behind the need to change from fossil fuels to hydrogen power, it is necessary to understand what that power is and how it works. Hydrogen is the most abundant and simplest element on earth. It is most commonly found as part of water. In its pure gaseous form it is extremely light, but when ignited in this state releases a large amount of energy in an explosion. In this violent reaction the hydrogen combines with free oxygen molecules in the atmosphere and creates water vapor. This is similar to the way gasoline is combined with air and ignited in an internal combustion engine in the cars used today and like with gasoline, the combustion of hydrogen has risks. In addition to the risk, some of the energy released in the reaction is lost in the form of sound and heat. As an alternative to burning, these same gases can be combined with the use of catalysts to extract the free electrons produced as liquid water is formed(Popovici and Hoble Dorel). Using cables connected to a fuel cell such as this, those electrons go through a circuit, generating electricity. This is more efficient than combustion because less energy is wasted in the form of sound and heat. Going further, greater efficiency for this reaction can be had the lower the temperature it is allowed to take place at, with 83% power at 25◦C(77◦ F)(Popovici and Hoble Dorel). As fuel cells are created with better heat management and
