Isotope Mass (amu) Percent Abundance Phosphorus-29 29 5% Phosphorus-31 31 71% Phosphorus-32 32 24%. The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Therefore, the effective nuclear charge towards the outermost electrons increases, drawing the outermost electrons closer. Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. Although phosphorus (15 P) has 23 isotopes from 25 P to 47 P, only 31 P is stable; as such, … Mendelevium is a chemical element with atomic number 101 which means there are 101 protons and 101 electrons in the atomic structure.

Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. Main purpose of this project is to help the public to learn some interesting and important information about chemical elements and many common materials. The chemical symbol for Indium is In. Platinum is one of the least reactive metals. The difference is a measure of the nuclear binding energy which holds the nucleus together. Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. Commercially, thallium is produced as a byproduct from refining of heavy metal sulfide ores. It is occasionally found in native form as elemental crystals. It is the 12 th most abundant element in Earth’s crust. Indium is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) stabilizes the free metal somewhat against further oxidation.
