Mercury Vs Yttrium Research Paper

Krypton and Arsenic are much less similar even though they are closer in the number of valence electrons. One major difference is that arsenic is a solid at room temperature, unlike Krypton. Arsenic also does not look like Krypton. Arsenic is more chemically reactive than Krypton as well. And lastly Krypton is non-toxic unlike arsenic.

These different elements

There are characteristics of Mercury that make it an appropriate target, and some that make it not. The different characteristics presented in the case are as follows:

The rare earth mineral/element yttrium is a soft-silvery, crystalline transition metal, which is naturally found stable in the half-life isotope form of 89Y (1). The element is found on the periodic table in group 3, and period 5, with an atomic number of 39, and can be considered ductile, odorless, lustrous, fairly reactive, and soluble in hot water (1, 2). Not only does this element have a hexagonal crystal structure, it has an atomic mass of 88.906u, has melting point of 1522°C, and a boiling point of 3338 °C(1-3). Yttrium is available in many different compounds, and forms just alone in metal (2, 3). Some of these forms include, but not limited to metal balls, turnings, wire, rocks, ribbon, rings,

The element mercury was known to ancient Egypt and China. They used it thinking it would prolong their life. It is one of the metal which is liquid in normal pressure and temperature. Which helps us to understand many parameters which are dependent on pressure and temperature. It was recognized as an element by A. L. Lavoisier in the 18th century. Some of the properties of the element are as follows.

Distinctly in the metals, starting at magnesium in the number 1 spot and going through until tin in number 6, the metals color becomes darker and darker. Magnesium is a very light silver, then comes scandium having a light silvery white color. Copper is an outlier in this situation as its very distinct color sets it apart from the other metals. Zinc is a medium silver grey and lead is a very dull grey. Tin being the darkest of the metals presented in this lab is still a silver grey, just a tinge darker than the

The anvil in the top left corner symbolizes tennessine being the second heaviest element known to mankind. The top right corner is tennessine’s atomic number (117), which is how many protons are in the nucleus of one atom. Below the atomic number, the hazard sign shows how radioactive tennessine is due to it not having a single stable isotope. To the right of the Ts, which is tennessine’s abbreviation, is a sign that says “halo!” this is referencing the fact that tennessine is in the halogen group of the periodic

Mercury is the smallest planet and is closest to the sun. It's a small, rocky planet that resembles the moon superficially. While the pockmarked surface and rugged terrain suggests a turbulent history, Mercury is no longer geologically active and has not been active for a long time. Mercury has a heavy iron-based core that is proportionally larger than that of any other planet, including Earth. Mercury has a much longer "day" than Earth. For every two Mercury-years, there are only three days. If earth rotated as slowly, each day would last about eight months. This really puts into perspective how slowly the small planet rotates. Despite its slow rotation, its magnetic field has become stronger and more dynamic since its first discovery. There has been a significant change in the geological instant of 35 years.

The physical characteristics are what helps make element 35 unique. It has 35 protons, 35 electrons, and 45 neutrons. Bromine’s boiling point is 138 °F [59 °C], and its freezing point is 19 °F [-7.2 °C]. Its atomic mass is 79.90 grams per mole. “It is the only nonmetallic element that is liquid at room temperature.” (Appelman, 2006) It has a reddish brown color and is not safe to touch or consume in any way. The foul smelling vapor from the element

Germanium weighs 72.61lbs, and the boiling point is 2830 degree Celsius. In addition, germanium has 9 isotopes, and the atomic mass i 72.59. However, “the element germanium is both metals and nonmetals. To be more precise, germanium is a very important element that light and shiny.

Mercury is extremely dangerous to humans due to its extreme conditions not suitable to human life. Missions to Mercury must be conducted with infallible safety standards to prevent incidents such as what has happened in the past. These safety standards must consider all possible circumstances in which measures must be taken. When doing missions on Mercury safety should be the number one priority.

Mercury: The element mercury has the chemical symbol Hg; it is a silver colour and is a liquid at room temperature. Mercury has a high density and surface tension and can easily break up into small droplets. Mercury can dissolve some metals resulting in amalgams, metal alloys of mercury. It is not soluble in water or most other liquids, but will dissolve in lipids (fats and oils). With fluctuations in temperature, mercury expands and contracts evenly with these changes and is classed as a non-combustible liquid. (Mercury characteristics)

Mercury may have a moon appearance from the outside, but with the planet’s unique components, gravity, size, orbit, and position in the Solar System, the planet may beg to differ. This paper will demonstrate knowledge to the reader of the physical components of the planet Mercury, its position in the Solar System, and how NASA studies this distant planet. How can you explore or study a planet, so close to Earth, yet too close to the Sun? How many Mercury days are considered an Earth day? How does this planet differ from the others? These may all be answered in the following paragraphs. The basics of Mercury will be discussed in more detail. Those include such topics as the planet’s orbit and position in the Solar System, atmosphere, size and the geography. Finally, the methods and techniques used by NASA to study Mercury, will be outlined.

Characteristic X-ray spectroscopy is similar to any other spectroscopy in that is excites electrons and then measurable energy is released and measured qualitatively and compared to well known facts and quantitative data is derived. X-rays can be excited by high energy beams made up of electrons, protons or even other x-rays. These beams are shot at the core of an atom and an inner electron excites and moves to an outer shell. When it calms back down it releases energy. This type of spectroscopy can be used to analyze and identify all elements on the periodic table except for hydrogen, helium and lithium. Under characteristic X-ray spectroscopy, there are two types: energy dispersive and wavelength dispersive. In energy dispersive x-ray spectroscopy, a semiconductor detector measures the energy of incoming protons while in wavelength dispersive x-ray spectroscopy a single crystal diffracts the protons and then the crystal is moved so that all emissions are visible. Once again a graph is made that is specific to an individual element and the element can be identified by the

Mercury is an element of the earth, and can take place naturally as well from manmade. Mercury continuously comes up towards the surface of the earth’s crust, because of the high temperature of the earth’s mantle, and this can make mercury a very mobile source. Surface rocks can contain high levels of concentrated mercury, which can add to the levels of emission standards of mercury. Natural sources can come from the earth crust, volcanoes, and erosion. Others are from weather, floods, and forest fires. This type of contamination is beyond mans control, and must be considered part of our atmosphere mercury levels. Scientist to this day have been struggling to separate the two from mans involvement to the natural output of mercury. Other
