Floridium, also known as Fd, is a new element with currently the highest atomic number of 173 and a mass of 486.9 g. Floridium is a part of the P-block and a superactinide , falling right after Neodymium (Nd). It is also highly nonpolar with Neodymium. Because it is a p orbital, it has a dumbbell shaped orbital with three possible orientations. In addition, it has an orange-brown color, is ductile and malleable, and has a boiling point of -57.8 Celsius. The element is quite rare, only found in the Southeast United States. As of 2016, Floridium has been recognized by scientists as an element. In 2012, scientists were exploring mines in the Southeast United States, mainly Florida, when they stumbled upon a shiny, new metal. Confused as to
Aluminum is the third most abundant element and most abundant metal in the Earth’s crust. Aluminum is never found in the free element state in nature. It
This experiment was conduct to investigate the fluorescent behaviour of Leucophor PAF and to investigate the quenching of QBS with NaCl. It was found that the Leucophor PAF indeed satisfied the characteristic to act as whitening agent. It was also found that the quenching of QBS with NaCl was a diffusion-controlled collision process.
Primo Levi’s personal relationship to his profession as a chemist shows that philosophically and psychologically, he is deeply invested in it. His book THe PeriOdic TaBLe shows that his methodology cannot be classified as either purely objective or purely subjective. He fits into the definition of dynamic objectivity given by Evelyn Fox Keller in her book Reflections on Gender and Science.
The tar creek mining site originally was owned by a Native American tribe, the Quapaw. The Quapaw wanted to keep these lands, but the Bureau of Indian Affairs deemed members opposing a transaction to mining companies “incompetent” (1). In such a case the business could continue and the Bureau of Indian Affairs sold the lands to mining companies. In essence these lands were stolen from the Quapaw because they were ripe for mining. These mines were then used from approximately 1891 to 1970. In the 79 years the mines were open 1.7 million metric tons (~3.75 billion pounds) of lead and 8.8 million metric tons (~19.4 billion pounds) of zinc were withdrawn from the mine (2). The entire area around Tar Creek is known as the tri-state mining area. This tri-state area was a massive source of metals. This area accounted for 35% of the all worldwide metal for a decade. It also provided the majority of metals the United States used in World wars I and II (3).
The Pebble mine project is a copper and gold deposit in its progressive expedition phase. The area of this project is located near the Bristol Bay region in southwest Alaska. The West side of Pebble contains approximately 4.1 billion metric tons. The East location contains 3.4 million metric tons. This range altogether contains 7.5 billion metric tons of high quality minerals. The debate of this project lies on the dangers to the surrounding environment, and the economic boost for the community.
In order to understand the controversy of fluoride, one must know the background . Fluoride is the ionic form of the element fluorine, an element abundant in the earth's crust (Borso 23). Fluoride is shown that is
The discovery of iron ore on the Mesabi Range can hardly be credited to one person. In 1890, however, it was the family of Lewis Merritt that discovered merchantable ore and opened the Mesabi to industry. Within three years, they owned several mines and had built a railroad leading to immense ore docks in Duluth. On the cusp of controlling a mining empire in northern Minnesota, they lost everything to business titan John D. Rockefeller.
With news of various metal detecting finds-on the beach or elsewhere-the hobby has slowly gained mainstream acceptance. One day soon, the general public may even dub it as cool. And hobbyists hanging out at the beach sweeping their treasure metal detectors this way and that, listening for sounds intently with their headphones, eyes never leaving the sand, isn't such a strange sight anymore.
One of the first attempts to locate and mine this copper was back in 1771 when the first mining expedition was organized. English miners were sent to the New World to locate and mine the copper heard of in Indian tales that had been passed along by the French. These miners had begun their excavation in a clay bank where they had previously seen trickling green copper-containing water with pieces floating in the water nearby. Unfortunately, the frozen roof of the tunnel had thawed and lead to a cave in resulting in the first failed attempt at mining copper in Michigan.
I was successful in my attempts to use floo powder to travel into your office, however as I forgot to close my eyes, it was quite a dizzying experience! Despite that, it was an enjoyable experience when I traveled through the fires with my whole body. Head-only floo powder transport was not as enjoyable. It made me feel sick having my head in a different place than my legs. Also, my knees hurt from kneeling on the hard stone floor beside the fire for that amount of time.
Amid the Civil War, gold mining operations ended as specialists got to be warriors. Just a single North Carolina mine stayed in operation: the Silver Hill Mine amongst Lexington and Denton. It created zinc, lead, silver, and gold. With the Confederate Army always needing ammo, excavators quickly burrowed the lead and silver to cast shots. Expelling the silver and gold from the lead was costly and tedious; a great part of the silver stayed ahead of the pack. It's said that numerous a Yankee officer kicked the bucket from North Carolina's silver and gold slugs.
Colorado also has a rich mining history which began in about 1859 with the discovery of gold and development of new reserves, Colorado’s present day industry is a modern, innovative, safe and environmentally responsible citizen that extracts a wide variety of minerals such as; gold, Marble, and gypsum from the earth, valued at more than $2 billion each year.

By adding up to 2%,of carbon it makes the steel tough and strong. Although it’s tough and strong, it is able to bend. To make sure that the metal doesn’t rust, it has a zinc coating on it. Iron is 26 on the periodic table,and considered an “transition metal,” meaning that it is ductile and malleable, and conduct electricity and heat. ... “Some other elements that are similar to iron are cobalt and nickel. They are the only elements known to produce a magnetic field.” Zinc is 30 on the periodic table and it is also a transition metal like iron. “The first iron used by humans is likely to have come from meteorites.” A meteorite is a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel. Meteors are believed to have been from the asteroid belt of Mars and
