Chromium is a steely-grey, lustrous, hard and brittle metal4 which takes a high polish, resists tarnishing, and has a high melting point. Elemental sulfur is a bright yellow crystalline solid at room temperature. Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating for the loss of or gain of electrons in their subsequent orbitals (we will examine those in the next section). Given the small differences between higher energy levels, this added stability is enough to shift an electron from one orbital to another. Melting point: 1966 . The metal is found in the Earths 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. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. The 18 Electron Rule is a useful tool to predict the structure and reactivity of organometallic complexes. From the Pauli exclusion principle, we know that an orbital can contain two electrons with opposite spin, so we place the second electron in the same orbital as the first but pointing down, so that the electrons are paired. rhodium Rh 45 102.906 12.41 1,964 3,695 palladium Pd 46 106.42 12.02 1,555 2,963 silver Ag .
