Dubnium, Arsenic, and Hydrogen Elements

• *= Arsenic can only melt at a higher atmospheric pressure creating a higher freezing and melting point than the boiling.
• **= Mohs is a scale of sharpness and hardness.
• ***=Ten to the sixth cm with omega

• Category: Metalloid
• Chemical Symbol: As
• Atomic Number: 33
• Atomic Mass: 74.92160
• Group: 15
• Period Number: 4
• Physical Description: Arsenic is grey and yellow, or metallic, though it is usually steel grey. It is very brittle and if it is heated rapidly, it will have a garlic smell.
• Physical and Chemical Properties: Density is 5.776 grams per cubic centimeter.
• Melting and Freezing Point: 1090K*
• Boiling and Vaporization Point: 887K
• Hardness: 3.5 mohs**
• Luster: Metallic luster
• Malleability: Easy Malleability
• Ductility: Low ductility
• Conductivity: Thermal conductivity- .502 w/cmk

Electrical conductivity- 0.0345 10^6/cm Ω***

• Availability and Isolation: Arsenic is found in minerals such as: realgar, orpiment, arsenolite, arsenopyrite and loellingite. Isolation is not needed to to arsenic's natural appearence.
• Uses: Arsenic is used to make led's, glass, rat poison, insecticides, laser lights

right out of electricity, and if small amounts are mixed with germanium, transistors can be made.

• History and Creation: In 1250, it is believed that, Albert Magnus, a German alchemist, found the, close to pure form, of arsenic by heating it with soap. Although, it was authentically reported in 1649 by Johann Schroeder. arsenic occurs natural, but is commonly obtained by heating arsenopyrite.
• How was it Named? Arsenic was named after the Latin word arsenicum, the Greek word arsonikon, and the Arabic word Az-zernikh.
• Cool Facts: 1.) Arsenic was mined by the early Chinese, Greek, and Egyptians. 2.) Arsenic is poisonous in all compounds. 3.) Arsenic can cause lung cancer if inhaled or skin cancer if touched.

4.) Arsenic is found in many household objects.

Arsenic

Conclusion

*= Due to its short half life.

**= W/cmk is an elements thermal conductance.

Dabnium, Arsenic, and Hydrogen have nothing in common besides the fact that they are atoms and that they contain protons. This is because dabnium only lasts for a short time, so not much is known about it, and it is man made. Arsenic is a natural occurring element found in minerals and its melting point is higher than its boiling point. Hydrogen is a natural element which happens to be the most abundant in the universe, and is used in many day to day objects that are vital to life. So, as seen here, dabnium, arsenic, and hydrogen are very different elements located on opposite sides of the periodic table.

• Physical Description: Unknown*
• Physical and Chemical Properties: Unknown*
• Melting and Freezing Point: Unknown*
• Boiling and Vaporization Point: Unknown*
• Hardness: Unknown*
• Luster: Unknown*
• Malleability: Unknown*
• Ductility: Unknown*
• Conductivity: Thermal conductivity of .58 w/cmk**
• Availability and Isolation: Close to none, half life is at most 34 seconds. Created by fusing neon and americium, or nitrogen and californium.
• Uses: Currently none, except for research.
• History and Creation: Albett Ghiorso discovered the element in 1967 by pelting a neon element with americium. In other projects of the same sort, scientists pelted nitrogen atoms with californium. both created dubnium only with different masses.
• How was it named? Dubnium was named after the place it was created, Dubna, Russia.
• Cool Facts: 1.) Dubnium is radioactive.
• 2.) Also created in Berkeley, California three laters.
• 3.) Only small numbers of dubnium have been produced.
• 4.) In 1992 IUPAC, declared that both the of the scientific teams in California and Russia would be given credit for the discoverey.

• Group: 1
• Period Number: 1
• Physical Description: None*
• Physical and Chemical Properties: Density- .00008988grams per cubic centimeter
• Melting and Freezing Point: 13.81K
• Boiling and Vaporization Point: 20.28
• Hardness: None*
• Luster: None*

• Conductivity: Thermal- .001815 w/cmk
• Availability and Isolation: Hydrogen is the most abundant element in our universe.
• Uses: The sun uses hydrogen to create energy. Hydrogen is being tested to be used as a power source for earth in the same the sun creates energy. Hydrogen can be used to create ammonia, hydrochloric acid, hydrogen peroxide, water, methane, sugar, superconductors (by using the liquid form of hydrogen), and if liquid hydrogen is mixed with liquid oxygen it makes a good rocket fuel.
• History and Creation: Robert Boyle was the first to produce hydrogen in 1671 by mixing iron and acids. Although, hydrogen wasn't recognized as an element until 1769 by Henry Cavedish.
• How was it named? Hydrogen was named after the Greek words "hydro" and "genes," meaning "water forming."
• Cool Facts: 1.) Hydrogen is the only element that is able to not have neutrons.
• 2.) Hydrogen is believed to be one of the three elements produced in the "Big Bang."
• 3.) Hydrogen reacts explosively with oxygen, chlorine, and flourine.
• 4.) Antihydrogen is the only antimatter made so far. Atoms of antihydrogen last a max of 1000 seconds or 17 minutes. Antihydrogen contains positrons and antiprotons, positively charged electrons and negatively charged protons respectively.
