Silicon is a hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor. How could iodine react to achieve noble gas configuration? Titanium can be used in surface condensers. The name samarium is after the mineral samarskite from which it was isolated. The function or functions it performs in the body: I- is used to make thyroid hormones. 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.
