Cadmium is a rare element discovered in 1817 by Frederick Strohmeyer as a byproduct of purifying zinc carbonate. It is found in small quantities as a minor component in most zinc ores. Cadmium is used primarily in batteries, plating, coatings, jewelry, television color tubes, and semiconductors, though its use has been reduced due to environmental concerns over its high toxicity.

Precious elements found on earth and their uses
Rhodium, platinum, gold, and osmium are precious metals found on Earth. Rhodium is used in catalytic converters, platinum is used in catalytic converters and jewelry, gold is used in jewelry, coins, and electronics, and osmium is used as a catalyst.
Rhodium (Megan Wogan)
Rhodium is a shiny silver-colored metal that was discovered in England in 1803. It has a high melting point of 1966°C and boiling point of 3727°C. Rhodium is very dense, with a density of 12.4 g/cm3, higher than water and steel. It is commonly found with nickel and copper in South America and Canada. Rhodium is primarily used for plating jewelry and coins and alloying with platinum and palladium for hardness.
the basics of chemistry
Chemistry is a science that evolved from alchemy and studies the structure and properties of matter. It has two main branches: inorganic chemistry, which examines differences between atoms, and organic chemistry, which studies carbon compounds. Matter exists in three states - solid, liquid, and gas. The periodic table organizes elements according to their atomic structure and properties, with elements in the same family having similar characteristics like valence electrons. Metals are good conductors while non-metals are not, and metalloids display properties in between.

Incline planes are sloping surfaces that work against gravity. Examples of inclined planes include ramps, stairs, and slides. Ramps and stairs are inclined surfaces that decrease the force needed to move an object upwards while increasing the distance traveled. Slides allow objects to move down at varying speeds depending on the angle of the inclined plane.
Neurobehavioural, neurochemical and neuromorphological effects of cadmium in ...
This study evaluated the neurobehavioral, neurochemical, and histopathological effects of cadmium chloride in male rats. 45 male rats were divided into 3 groups - a control group and 2 groups exposed to low-dose (5mg/L) and high-dose (50mg/L) cadmium chloride in drinking water for 60 days. Behavioral tests showed increased activity and decreased memory in exposed groups. Biochemical analysis found decreased acetylcholinesterase and increased lipid peroxidation in brains of exposed rats. Histopathological examination found neurodegeneration in brains of exposed rats. The study suggests that cadmium exposure can cause neurological damage and behavioral impairments due to oxidative stress.

Estimating Annual Cadmium Load
Three researchers from Thailand presented on their study estimating annual cadmium load into Songkhla Lake via surface runoff. They used the TREX model to simulate cadmium transport under different scenarios. The model was calibrated and validated against measured data with relative errors of 5-30%. Scenario analysis found that increasing fertilizer use or changing fertilizer type could increase cadmium levels in runoff. The U-Tapao watershed was identified as highest risk due to soil and land use factors. Reducing cadmium in fertilizers could significantly lower cadmium transport into the watershed.

Cadmium (Rebekka Meeks)
Friedrich Stromeyer discovered cadmium in 1817 while studying calamine. Cadmium is a soft, silvery-white metal that occurs naturally as a byproduct of zinc mining. It has many industrial uses, including in nickel-cadmium batteries, solar panels, and nuclear reactors. Cadmium is toxic to humans and environmental exposure can occur through cigarette smoke, coal burning, contaminated food/water, and landfill runoff.
Cadmium (Jeremy Willett)
Cadmium is a soft, bluish-white metal that was first discovered in 1817 by German chemist Friedrich Strohmeyer while studying calamine. It has several important industrial uses including in nickel-cadmium batteries, as an anti-corrosive coating for steel, and in semiconductors. However, cadmium is also toxic to humans and accumulates primarily in the kidneys, where high levels can lead to kidney failure. While cadmium intake has decreased in recent decades, it remains a concern due to negative health effects. Cadmium is obtained as a byproduct during production of other metals like zinc, copper and lead.

A pilot study on effect of copper and cadmium toxicity in Tilapia Mossambicus
Cu and Cd is trace element for most organisms including fish, but above certain limit Cu and Cd will be toxic. The present study was conducted to evaluate the toxic effect of Cu and Cd on Tilapia mossambicus via estimating the acute 96h median lethal concentration (LC50) value. A total 120 number of Tilapia mossambicus fingerlings were subjected to 12 numbers 20-L aquaria. Fish were exposed to 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0mg Cu and Cd/L for 4 days. Each dose was represented by two aquaria. Fish was daily observed and dead fish were removed immediately. The data obtained were evaluated using Behrens-Karber’s Method. The 96 h LC50 value of Cu for Tilapia mossambicus was calculated to be 6.0mg Cu/L with Behrens-Karber’s Method. The 96 h LC50 value of Cd for Tilapia mossambicus was calculated to be 4.8mg Cd/L with Behrens-Karber’s Method. The behavioral changes of Tilapia mossambicus were primarily observed. It could be concluded that Tilapia mossambicus species slightly sensitive to Cu and Cd when compare both metal cadmium is more toxic than copper for the fish species.

cadmium ~ juan
Cadmium is a soft metal that is a byproduct of zinc production. It can cause health issues when inhaled or ingested, as the body absorbs it and stores it in organs like the liver and kidneys. Dental amalgam fillings contain cadmium, which can stain teeth and impact periodontal health over time. Cadmium poisoning was responsible for the Itai-itai disease that affected women working in battery factories in Japan, causing bone and kidney problems. Mild cases are treated with supplements, while more severe cases require hospitalization, supplements, and potentially chelation therapy or dialysis.

Cadmium is a rare, stable element discovered in 1817 by Frederick Strohmeyer. It is found in small quantities as a minor component in most zinc ores and is used mostly in batteries, jewelry, coatings, and plating, as well as for color tubes in televisions and as a semiconductor.

Incline planes are sloping surfaces that work against gravity. Examples of inclined planes include ramps, stairs, and slides. Ramps and stairs are inclined surfaces that decrease the force needed to move an object upwards while increasing the distance traveled. Slides allow objects to move down at varying speeds depending on the angle of incline without applying any force.

- 1. Cadmium By Sarah Crosby and Emily Kate Finn
- 2. Group, Period, and Number , Symbol Cadmium is in group 12 and period 5 on the periodic table. It is the 48th element on the periodic table of the elements and its symbol is Cd.
- 3. Who discovered it and when? Cadmium was discovered in 1817 by Frederick Strohmeyer, a German chemist. He discovered it while he was purifying some samples of zinc carbonate.
- 4. Quantities? Cadmium is found is small quantities. Cadmium is a rare element. It is found in minor components in most zinc ores. The amount of Cadmium has also been cut down because of its high toxicity and environmental concerns.
- 5. Uses and Value Cadmium is used mostly in batteries and jewelry. Other uses for Cadmium are coatings and plating as well as a stabilizer for plastic . It is used in the color tubes for televisions. It is used as a semi-conductor which means that cadmium can be bonded with other elements to form new elements.
- 7. Stable or Unstable? Cadmium is a stable element!
