As with other actinide elements, berkelium tends to accumulate in the skeletal system. Berkelium is artificially produced, and has only been produced in relatively small amounts.

Source: Berkelium is produced in miniscule amounts in nuclear reactors such as the High Flux Isotope Reactor at Oak Ridge National Laboratory, Tennessee by nuclear bombardment of plutonium, curium or americium with alpha particles.

Berkelium is one of 15 actinides, elements with atomic numbers 89 to 103. Because these rare, heavy metal isotopes are radioactive, they are difficult to study.

Berkelium is produced by bombarding uranium or plutonium with neutrons in a nuclear reactor, and can be separated from other products of these reactions with relative ease, compared to some of the other transuranic elements.

Four of the elements are named after planets (Earth – in the form of tellurium, Mercury, Neptune and Uranus). A further two are named after dwarf plants (Pluto and Ceres), while one after a star (helium from the Greek for the sun – Helios) and another after an asteroid (Pallas) feature on the periodic table.

americium (Am) from America,and germanium (Ge) from Germany, then also indium (In) was named in honor of India. quote from the original communication2 of Ferdinand Reich and Theodor Richter from 1863.

* The village gave its name to four elements in the periodic table — the rare minerals Yttrium, Terbium, Erbium and Ytterbium, and is the place in the world where the most elements have been discovered.

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. It is the lightest element that has not yet been synthesized.

Element 119 is expected to be a typical alkali metal with a +1 oxidation state.

element astatine

Unbinilium, also known as eka-radium or simply element 120, is the hypothetical chemical element in the periodic table with symbol Ubn and atomic number 120.

Corbomite (symbol Ct) is a chemical element, atomic number 140 on the periodic table.

Unbihexium, also known as element 126 or eka-plutonium, is the hypothetical chemical element with atomic number 126 and placeholder symbol Ubh.

For chemistry students and teachers: The tabular chart on the right is arranged by the discovery year. The oldest chemical element is Phosphorus and the newest element is Hassium.

Fast Facts: The Most Expensive Natural Elements

• The most expensive natural element is francium, but it decays so quickly it can’t be collected to be sold.
• The most expensive natural element that is stable enough to purchase is lutetium.
• Atoms of synthetic elements cost millions of dollars to produce.

A necessary prerequisite to the construction of the periodic table was the discovery of the individual elements. Although elements such as gold, silver, tin, copper, lead and mercury have been known since antiquity, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous.

Pure sulfur has no smell. The stink associated with the element comes from many of its compounds, according to Chemicool. For example, sulfur compounds called mercaptans give skunks their defensive odor. Rotten eggs and stink bombs get their distinctive aroma because of hydrogen sulfide.

Sulfur is low in toxicity to people. However, ingesting too much sulfur may cause a burning sensation or diarrhea. Breathing in sulfur dust can irritate the airways or cause coughing. It can also be irritating to the skin and eyes.

Elemental sulfur is used in black gunpowder, matches, and fireworks; in the vulcanization of rubber; as a fungicide, insecticide, and fumigant; in the manufacture of phosphate fertilizers; and in the treatment of certain skin diseases.

First, the rotten egg smell that you are experiencing is most likely hydrogen sulfide (H2S) gas. While extremely high levels of hydrogen sulfide can indeed be harmful, even deadly, H2S is one of those chemicals that can be detected by the nose at an extremely low level.

Sewer gas contains methane, ammonia, and hydrogen sulfide which are all toxic when inhaled. If exposed to very high concentrations of sewer gas, a person can asphyxiate and die. More common symptoms of exposure to sewer gas include nausea, eye irritation, and difficulty breathing.

At low levels, hydrogen sulfide causes irritation of the eyes, nose, and throat. Moderate levels can cause headache, dizziness, nausea, and vomiting, as well as coughing and difficulty in breathing. Higher levels can cause shock, convulsions, coma, and death.

Hydrogen sulfide is the primary gas in sewer gas. According to research , hydrogen sulfide has shown to be toxic to the oxygen systems of the body. In high amounts it can cause adverse symptoms, organ damage, or even death.

Carbon monoxide (CO) is a gas that can kill you quickly. It is called the “silent killer” because it is colorless, odorless, tasteless and non- irritating.

The first step in getting rid of your sewer gas problem can be easily accomplished by an odor detection test commonly referred to as a “smoke” test. This process involves isolating the sewer system by pushing colored smoke through a roof stack and blocking off the drain line with a test ball.

Hydrogen sulfide gas is also known as “sewer gas” because it is often produced by the breakdown of waste material. However, at higher levels, your nose can become overwhelmed by the gas and you cannot smell it. At higher levels, hydrogen sulfide gas can make you sick and could be fatal.

Exposure to low levels of hydrogen sulfide causes irritation of the eyes and respiratory tract. Other symptoms include nervousness, dizziness, nausea, headache, and drowsiness. This gas smells like rotten eggs, even at extremely low concentrations.

Answer: Only under extremely unusual circumstances. Although hydrogen sulfide is a toxic gas, it will not harm people at the concentrations that exist in a house with sewer gas odor problems. Studies have shown that hydrogen sulfide has a depressant effect on the central nervous system in concentrations above 150 ppm.

The trusty non-toxic combo of baking soda and vinegar can clean drains naturally. Add one cup of baking soda to the clogged toilet or slow drain, then wait a few minutes. Follow with two cups of vinegar.
