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.

Now is the time to understand more, so that we may fear less.”-Marie Curie. “Nothing in life is to be feared, it is only to be understood. Strap on those safety gloves to these 42 explosive facts about Marie Curie. Raised in a time and place where higher education for women was not just taboo but often illegal, no one can accuse Marie Curie of having an easy walk to the podium. For the Marie, the path to knowledge was fraught with starvation, sexism, war, love, and, yes, the occasional sex scandal. And she didn’t stop there: in her widowhood, Curie went to win another Nobel prize, thereby cementing herself in history as a role model for women in STEM.īehind her scientific honors, however, there lays a historical struggle. The Polish-born scientist formed one-half of the Curie power couple, who went on to win the Nobel Prize for their discovery of radium. Marie Curie requires little introduction: her name itself has become a shorthand for the archetypical super-smart and trailblazing female scientist.
