Question

Write the uses of silicon and antimony.

Answer 1

$\mathrm{Silicon}\left(\mathrm{Si}\right):$

• Silicon (Si) is a close relative of $\mathrm{carbon}\left(\mathrm{C}\right)$in the periodic table.
• The element could be traced universally in our world but is not found individually in our environment.
• A silicon Atom comprises 14 electrons

Uses of Silicon:

• The element is a major constituent in ceramics and bricks.
• Being a semiconductor, the element is put into use for making transistors.
• Silicon is widely used in computer chips and solar cells.
• It is a vital component of Portland cement.
• Silicon is used in the production of fire bricks

$\mathrm{Antimony}\left(\mathrm{Sb}\right):$ Antimony is a semi-metallic chemical element with an atomic number 51 and the symbol $\mathrm{Sb}$ in the Periodic Table.

• The Latin name of Antimony is $\mathrm{Stibium}$. It is generally found in two forms namely metallic form and non-metallic form.
• Antimony compounds are used since ancient times as a component in cosmetics.
• It is naturally found in Earth’s crust in the ores of $\mathrm{stibnite}$.

Uses of $\mathrm{Antimony}\left(\mathrm{Sb}\right):$:

• Pure antimony is used in the manufacturing of certain semiconductors like infrared detectors and diodes.
• It is used to harden lead and increase its durability.
• Batteries consist of antimony for smooth functioning.
• It is also used to make small arms & bullets.
• It is a very good flame retardant.
