Silicon 29 Metal (Silicon-29) is a stable (non-radioactive) isotope of Silicon. See below table for ENSDF Citation and Half Life. It is both naturally occurring and produced by fission. Silicon 29 Metal is one of over 250 stable metallic isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications. Silicon Metal is also available in ultra high purity and as nanoparticles. For thin film applications it is available as rod, pellets, pieces, granules and sputtering targets and as either an ingot or powder. Silicon Metal 29 isotopic material is generally immediately available. Additional technical, research and safety (MSDS) information is available.

Silicon is a Block P, Group 14, Period 3 element. The electronic configuration is [Ne] 3s2 3p2. In its elemental form silicon's CAS number is 7440-21-3. The silicon atom has a radius of 117.6.pm and it's Van der Waals radius is 210.pm.
