Michael asks…

When did people first discover that organism are composed of water?

I’m talking about all of the organism mostly composed of. water i.e. protoplasm,etc.When did people firstly discover or realize that fact and who did?

New Niche Finder answers:

The Greeks considered water to be one of the basic element the body was made from. After all any one who dried food for storage realized how much water mass was lost in the process.

How are new elements discovered?

How are new elements discovered?

New Niche Finder answers:

At this point in time, no new elements are “discovered.” In the early days of chemistry there were many elements waiting to be discovered so that they could occupy the holes in the periodic table. But today, there are no holes. All the new elements being produced are super-heavy elements beyond uranium.

These elements aren’t “discovered.” There is a concerted effort to “make” these new elements. The process involves particle accelerators and flinging two particles together at high speed in hopes that the collision will result in the making of a super-heavy element. The new element, if it is produced, doesn’t hang around for long, and quickly decays. The scientists examine the results of this decay for tell-tale signs that they made a new element. Only when there is a consensus among the scientists that the nuclear detritus came from a new element, is it announced.

The statement by Kaynex, ” Theoretically, there are no new stable elements yet to be discovered.” isn’t actually true. While the heavy elements filling out the rest of period 7 are not stable, there is a theoretical basis for an “island of stability” in which the super-heavy elements yet to be made will be more stable than the ones closer to uranium.

Who discovered the element radium?

New Niche Finder answers:

Radium (Latin radius, ray) was discovered by Marie Skłodowska-Curie and her husband Pierre on December 21, 1898 in a uraninite sample. While studying the mineral, the Curies removed uranium from it and found that the remaining material was still radioactive. They then separated out a radioactive mixture consisting mostly of compounds of barium which gave a brilliant green flame color and crimson carmine spectral lines that had never been documented before. The Curies announced their discovery to the French Academy of Sciences on 26 December 1898. The naming of radium dates to circa 1899, from French radium, formed in Modern Latin from radius (ray), called for its power of emitting energy in the form of rays. In 1910, radium was isolated as a pure metal by Curie and André-Louis Debierne through the electrolysis of a pure radium chloride solution by using a mercury cathode and distilling in an atmosphere of hydrogen gas.[8] The Curies’ new element was first industrially produced in the beginning of the 20th century by Biraco, a subsidiary company of Union Minière du Haut Katanga (UMHK) in its Olen plant in Belgium. UMHK offered to Marie Curie her first gram of radium. It gave historical names to the decay products of radium, such as radium A, B, C, etc., now known to be isotopes of other elements.
On 4 February 1936, radium E (bismuth-210) became the first radioactive element to be made synthetically in the United States. Dr. John Jacob Livingood, at the radiation lab at University of California, Berkeley, was bombarding several elements with 5-MEV deuterons. He noted that irradiated bismuth emits fast electrons with a 5-day half-life, which matched the behavior of radium E.
The common historical unit for radioactivity, the curie, is based on the radioactivity of 226Ra.

Lisa asks…

Who is the discoverer of the element Zinc and where did they discover it?

I need to know for a Science portfolio, please I saw someone elses question about this, I don’t want to know extra info, I just want to know who discovered it and where, thanks.

New Niche Finder answers:

The discovery of the elements known to exist today is presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately defined. There are no written records for the discoveries of the first few elements that were known in antiquity.

Given is each element’s name, atomic number, year of first report, name of the discoverer, and some notes related to the discovery.

29 Copper 9000 BCE 6000 BCE Middle East Anatolia Copper was probably the first metal mined and crafted by man.[1] Earliest estimates of discovery of copper suggest around 9000 BCE in the Middle East. It is one of the most important materials to humans throughout the entire copper and bronze ages. Copper beads dating from 6000 BCE were found in Çatal Höyük, Anatolia.[2]
79 Gold before 6000 BCE 5500 BCE Middle East Egypt Archaeologists suggest that first use of gold began with the first civilizations in the Middle East. It may have been the first metal used by humans. Oldest remaining gold jewelry is that in the tomb of Egyptian Queen Zer.[3][4]
82 Lead 7000 BCE 3800 BCE Near East Abydos It is believed that lead smelting began at least 9000 years ago, and the oldest known artifact of lead is statuette found at the temple of Osiris on the site of Abydos dated circa 3800 BC.[5] Lead was first purified and clearly differentiated from tin by medieval Arabic chemists[6]
47 Silver before 5000 BCE ~4000 BCE Asia Minor ? Estimated to have happened to shortly after that of copper and gold.[7][8]
26 Iron before 5000 BCE 4000BCE ? Egypt There is evidence that iron is known from before 5000 BCE.[9] The oldest known iron objects used by humans are some beads made from meteorite iron, in Egypt, made about 4000BCE. Discovery of smelting around 3000 BCE lead to the prominence of use of iron for tools and weapons, which lead to the start of iron age around 1200 BCE.[10]
6 Carbon 3750 BCE ? Egyptians and Sumerians ? Earliest known use of charcoal for the reduction of copper, zinc and tin ores in the manufacture of bronze, by the Egyptians and Sumerians.[11] Diamonds were probably known as early as 2500 BCE[12] First true chemical analyses were made in the 18th century CE,[13] and in 1789 was listed by Antoine Lavoisier as an element.[14]
50 Tin 3500 BCE 2000 BCE ? ? First smelt in combination with copper around 3500 BCE to produce bronze and brass.[15] Oldest artifacts date around 2000 BCE.[16] First purified and clearly differentiated from lead by medieval Arabic chemists (ca. 700–1400 CE).[6]
16 Sulfur before 2000 BCE ? Chinese/Indians ? First used at least 4000 years ago.[17] First identified as an element by Geber (ca. 800 CE).[18] Also recognized as an element by Antoine Lavoisier in 1777.
80 Mercury before 2000 BCE 1500 BCE Chinese/Indians Egypt Known to ancient Chinese and Hindus before 2000 BC, and found in Egyptian tombs dating from 1500 BCE.[19] First identified as an element by Geber (ca. 800 CE).[18]
30 Zinc before 1000 BCE 1000 BCE Indian metallurgists Indian subcontinent Extracted as a metal since antiquity by Indian metallurgists before 1000 BCE, but the true nature of this metal was not understood in ancient times. Identified as a unique metal by the metallurgist Rasaratna Samuccaya in 800 CE[20] and by the alchemist Paracelsus in 1526.[21] Isolated by Andreas Sigismund Marggraf in 1746.

33 Arsenic 800 CE (ca.) ? 800 CE (ca.) Geber Geber or A.Magnus Geber Discovered and isolated by Geber, who described its preparation in his Liber Fornacum, ca. 800 CE.[24][25][26] Albertus Magnus was the first European to isolate the element in 1250.[22][23] In 1649, Johann Schröder published two ways of preparing elemental arsenic.
51 Antimony 800 (ca.) 800 (ca.) Geber Geber Discovered and isolated by Geber ca. 800 CE.[24][25] Basilius Valentinus was the first European to describe the element around 1450.[22][23] First description of a procedure for isolating elemental antimony in 1540 by Vannoccio Biringuccio.
83 Bismuth 800 (ca.) 1753 Geber C.F.Geoffroy Discovered by Geber ca. 800.[25][27] Later described in writings attributed to Basilius Valentinus around 1450.[22] Definitively identified by Claude François Geoffroy in 1753.[23]

David asks…

Where was the element discovered?

New Niche Finder answers:

It depends on which element. Different elements were found by different people. Not one person discovered all the elements and put them on there.. It took time and finally Mendeleev sorted out the periodic table to show all the elements.
