How many radioactive elements are there on the periodic table




















Radium is a radioactive metal that can be found at varying levels throughout Vermont and the entire Earth—in soil, water, rocks, plants and food. Learn more about radium in drinking water. Radon is a radioactive gas that has no color, smell or taste. Over billions of years, uranium decays into radium, and eventually into radon.

Learn more about radon in indoor air and in drinking water. Polonium Po is a radioactive material that occurs naturally at very low concentrations in the environment. It can be produced in university or government nuclear reactors, but it requires expertise to do so. Po only becomes a radiation hazard if it gets inside the body through breathing, eating or by entering through a wound. This internal contamination can cause irradiation of organs, which can result in serious medical symptoms or death.

Po and its radiation do not get through intact skin or membranes. It is not an external hazard to the body. Plutonium was named after the planet, Pluto. Trinity was the code name for the very first detonation of a nuclear bomb on July 16th, in New Mexico. Plutonium bombs create a pyrocumulus mushroom cloud.

It is highly radioactive, and the symbol was also invented at the University of California Berkeley. Our image depicts the four scientists who discovered the element riding an atomic bomb in outer space.

The atomic bomb represents the actual discovery of the element. During WWII, the scientists were testing the bombs when they produced americium. The element is now tested for use in the international space station, hence the picture being set in outer space. Polonium and Radium are included because Marie Curie discovered these elements. The radioactive symbol is there because Marie Curie worked with radioactive elements.

Since Marie was from Poland and her husband Pierre was from France, we chose to include the flags from those countries. The rings signify the love and marriage between Marie and Pierre. Green is the background because that was Marie's favourite colour. The initials of our school are also included.

Back to the top. Each artist contributed to different parts of the artwork. The stars are the Andromeda constellation, where traces of Promethium are found.

Promethium was given its name from the Greek Titan Prometheus who stole fire from the gods to give to the humans. Prometheus' torch holds the star in the constellation where Promethium was found. The lake colour is symbolic of the chemical compound of promethium in luminous paint and the power plants represent how promethium is not naturally occurring on Earth, but must be manufactured. The mountain in the background is Mount Currie, which overlooks our town of Pemberton. Stacey Deneka Artist: Abhimanya Navaratnam.

Berkelium was first discovered on December, , in the University of California at Berkeley. I chose to represent as much information of the element onto the hexagon while remaining true to the identity of berkelium.

A significant feature is the presence of the logo for the University of California at Berkeley. The main features present in the regular logo are replaced by information that are true to berkelium. Californium was first discovered at Berkeley, California in the s.

It is a very strong neutron source and is used to find gold and silver ores through neutron activation. The design of the element took place in fall of so the strong note on my element artwork symbolizes recent events in my community including the Borderline shooting and local wildfires in November in Our recovery is strong, and representing my strong community in an international setting is an honor.

Einsteinium, named after Albert Einstein, is a synthetic element discovered in during examination of debris of the first hydrogen bomb. Einsteinium was discovered by scientist Albert Ghiorso and his team. A mushroom cloud and radioactive hazard sign represents how it was discovered, and its radioactive properties.

Albert Ghiorso has been placed in front with silhouettes to represent his team. The beach setting and ocean background represents where the bomb was tested: the Pacific Ocean.

The use of glitter represents the small amount of element created, and also that it glows blue due to energy released during radioactive decay. The idea for the artwork starts first with the green tile because fermium is radioactive and radiation is commonly associated with the green colour. Secondly, since it was discovered at the Ivy Mike Test Centre where a thermonuclear device was also tested, I added a mushroom cloud to represent the dangerous process that first created fermium. Westwood pays homage to the great thinker, Mendeleev, in our design for mendelevium.

He formulated the reasons science lovers are celebrating this year, an early version of periodic table. Synthesized by crashing einsteinium with alpha particles in a particle accelerator, mendeleevium was discovered by Albert Ghiorso, Glenn T. Harvey, and Stanley G. Thompson in at the University of California, Berkeley. The design of Westwood's Chem 35 class ties all these aspects and history behind the seemingly simple element. Made by combining acrylic, watercolour, and digital techniques, we hope to honour the mysterious element and the great man it is named after.

The medium of my illustration is a colored pencil outlined with Sharpie. The illustration depicts the four discoverers of the element nobelium: Albert Ghiorso, Glenn T. Seaborg, Torbjorn Sikkeland and Georgy Flerov. Alfred Nobel, the chemist who discovered dynamite and founded the Nobel Prize foundation, is also featured since element was named after him. Behind each of the figures are the flags of their nationality. Rutherfordium was first discovered in Dubna, Russia, in by a team of scientists led by Georgy Flerov.

Sometimes the longest-lived half-life of a radionuclide is not the most useful or affordable. Certain common isotopes are available even to the general public in small quantities in most countries. Others on this list are available by regulation to professionals in industry, medicine, and science:.

Gamma Emitters. Beta Emitters. Alpha Emitters. Multiple Radiation Emitters. Radioactivity exists in nature, but radionuclides can cause radioactive contamination and radiation poisoning if they find their way into the environment or an organism is over-exposed.

Typically, radiation exposure causes burns and cell damage. Radiation can cause cancer, but it might not appear for many years following exposure.
