By the end of this module, you will be able to: Describe the general preparation, properties, and uses of the metalloids Describe the preparation, properties, and compounds of boron and siliconA series of six elements called the metalloids separate the metals from ...
these elements generally have intermediate energies of ionisation and values of electronegativity metalloids are known to form amphoteric or weakly acidic oxides. these elements have the ability to form metallic alloys. many of the other physical and chemical properties of metalloids, in essence, are ...
In this book we are concerned with the properties of compounds which contain metal-carbon bonds. Traditionally organometallic chemistry includes the carbon compounds of the metalloids boron, silicon and arsenic, but excludes those of phosphorus and of other more electronegative elements. Metal carbonyls ...

Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (such as aluminum, manganese, nickel or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic, or silicon. These additions produce a ...

This reagent gained importance especially after preliminary investigations dated from the 1960s, which demonstrated its high stability in acidic medium and high selectivity and efficiency in complex formation reactions with metals and metalloids. The presence of two sulfur atoms and one phosphorus atom ...
