The availability of suitable substitutes for a given commodity. A higher recycling rate may reduce risk to supply. The percentage of a commodity which is recycled. The number of atoms of the element per 1 million atoms of the Earth’s crust. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems.ĭata for this section been provided by the British Geological Survey.Īn integrated supply risk index from 1 (very low risk) to 10 (very high risk). Where more than one isotope exists, the value given is the abundance weighted average.Ītoms of the same element with different numbers of neutrons. This is approximately the sum of the number of protons and neutrons in the nucleus. The mass of an atom relative to that of carbon-12. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase.ĭensity is the mass of a substance that would fill 1 cm 3 at room temperature. The temperature at which the liquid–gas phase change occurs. The temperature at which the solid–liquid phase change occurs. ![]() The arrangements of electrons above the last (closed shell) noble gas. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). ![]() The atomic number of each element increases by one, reading from left to right.Įlements are organised into blocks by the orbital type in which the outer electrons are found. Members of a group typically have similar properties and electron configurations in their outer shell.Ī horizontal row in the periodic table. Marie Curie inspired others to continue her work.A vertical column in the periodic table. But it was and because of this Marie became very ill and died. Marie worked hard to find a cure for cancer - nobody knew that working with radium was dangerous. The first woman professor the university ever had!Ī few years later, Marie won another Nobel Prize and the university built her a laboratory. Marie took over his teaching job at the University of Paris - she was so good they made her a professor. Marie and Pierre found that radium could help the body fight cancer cells. Marie was the first woman ever to receive this! They were given the most important prize in the world for science: the Nobel Prize. ![]() They studied the light and heat it gave off and called this radioactivity. They discovered a new element that gave off rays of heat and light - they called this radium. They worked together to find out about the tiny parts, called elements, that make up everything in our Universe. When Marie lived in Poland girls were not allowed to go to university, so her parents had to send her in secret. One woman, Marie Curie, helped change the lives of people all over the world and showed that girls are as good at science as boys! We know today this is nonsense, but not then. There was a time when people didn't think that women were clever enough to work in science. ![]()
