What is beryllium and barium?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). … They are smaller than the alkali metals of the same period, and therefore have higher ionization energies.
Is beryllium a rare earth metal?
Beryllium is not strictly a rare earth but its scarcity and versatility makes it a much sought-after metal. … The amount of beryllium metal discovered in Xinjiang is estimated to exceed 4,000 tons.
What is Cadmium used for?
Common industrial uses for cadmium today are in batteries, alloys, coatings (electroplating), solar cells, plastic stabilizers, and pigments. Cadmium is also used in nuclear reactors where it acts as a neutron absorber.
Is beryllium harmful to humans?
Direct contact with beryllium fumes or dusts may injure the exposed areas of the body, such as the eyes or the skin. Skin sensitization may also occur. Beryllium is also a known cancer causing substance, with higher levels of lung cancer being reported.
Is RA a representative element?
Rubidium (Rb), Cesium (Cs), Francium (Fr), Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra).
What is nitrogen family?
The nitrogen family includes the following compounds: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). … The nitrogen family includes the following compounds: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi).
What is the last element in Period 4?
krypton These are scandium, titanium, vanadium, chromium, manganese, iron, nickel, copper and zinc. At the last of this period there is a noble called krypton. Thus krypton is the last element of the ${4^{th}}$ period.
Why is beryllium used in aircraft?
Beryllium alloys are used in automobile components and airplane equipment to ensure the reliable operation of vital equipment and to enhance fuel efficiency. Beryllium helps get us from here to there. … These weight savings, in turn, make planes more fuel efficient which results in reduced exhaust emissions.
What foods contain beryllium?
Beryllium, as a chemical component, is found naturally in some food. The concentration of beryllium in both raw carrots and field corn grown in the United States is less than 25 micrograms (µg) (1 µg=1 millionth of a gram) in a kilogram (kg) of the fresh vegetables.
What is the use of boron?
People take boron supplements as medicine. Boron is used for boron deficiency, menstrual cramps, and vaginal yeast infections. It is sometimes used for athletic performance, osteoarthritis, weak or brittle bones (osteoporosis), and other conditions, but there is no good scientific research to support these other uses.
What is the rarest element on earth?
astatine A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
Which country has most rare earth?
China China dominates the rare earths market globally. About 35% of rare earth global reserves are in China, the most in the world, according to the United States Geological Survey.
Why is beryllium so expensive?
Beryllium is primarily produced using bertrandite and beryl ores. … High-purity beryllium is expensive owing to its properties such as high stiffness, lightweight, and high elastic modulus.
Why is cadmium so toxic?
Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. …

What does cadmium do to your body?
Occupational exposure to cadmium can lead to a variety of adverse health effects including cancer. Acute inhalation exposure (high levels over a short period of time) to cadmium can result in flu-like symptoms (chills, fever, and muscle pain) and can damage the lungs.
Why is cadmium banned?
The ban on cadmium in jewelry is intended to protect consumers, particularly children, from the toxic metal, which has been increasingly showing up in inexpensive costume jewelry imported from China.
What disease does beryllium cause?
Chronic Beryllium Disease, sometimes called berylliosis, is a chronic granulomatous lung disease caused by an immunological response from exposure to beryllium. CBD can progress to a serious and life-threatening disease if left undiagnosed and beryllium exposure continues.
Is beryllium copper toxic?
Toxicity. In solid form and as finished objects, beryllium copper presents no known health hazard. However, inhalation of dust, mist, or fume containing beryllium can cause the serious lung condition chronic beryllium disease, which restricts the exchange of oxygen between the lungs and the bloodstream.
Is beryllium oxide toxic?
* Beryllium Oxide is a CARCINOGEN–HANDLE WITH EXTREME CAUTION. … * Beryllium Oxide can irritate and burn the skin. Higher exposure may cause skin ulcers to develop. * Breathing Beryllium Oxide can irritate the nose, throat and lungs.
What family is Xenon?
noble gases Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
Which is P block elements?
Consequently there are six groups of p–block elements in the periodic table numbering from 13 to 18. Boron, carbon, nitrogen, oxygen, fluorine and helium head the groups. Their valence shell electronic configuration is ns2np1-6(except for He). The inner core of the electronic configuration may, however, differ.
What is the special name of group 18?
The noble gases The noble gases are a group of chemical elements that make up Group 18 on the periodic table.
What is Group 14 called?
carbon group element carbon group element, any of the six chemical elements that make up Group 14 (IVa) of the periodic table—namely, carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
What is fluorine family?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
