SODIUM CHLORIDE

Sodium chloride is a compound known for involving an ionic bond in its formation and the chemical formula for this ionic compound is NaCl. The chemical formula and the scientific name of any compound display information about the elements involved in the formation of that compound. Along with this, it also displays the simplest ratio in which the elements are combined to form the compound. Thus, from the sodium chloride chemical formula it is clear that the elements involved in its formation are sodium(Na) and chlorine(Cl).

SODIUM CHLORIDE cont.

Ionic compounds can be defined as chemical entities formed by the combination of two or more elements as a result of the electron transfer between them. This chemical bonding occurring between the different elements of such compounds is termed electrovalent/ionic bonding. During the process of the formation of the ionic compounds, the electropositive species loses the electron(s) which are further gained by the electronegative species. In ionic compounds, the positively charged atoms are referred to as cations whereas the negatively charged atoms are referred to as anions.

Facts about Soduim Chloride...

  • Sodium Chloride is the only family of rocks regularly eaten by people.
  • It is also one of the most abundant mineral on Earth.
  • Every cell in your body contains salt.
  • Your body needs 200 mg of salt per day to be healthy.
  • Only 6% of the salt that the US uses is used as salt. In fact, 17% is for keeping ice off the road in winter.

Diamond

Diamonds are unique materials that are made up of pure crystalline structures from the element carbon. Diamonds are created under immense heat and pressure deep below the Earth’s surface which contributes to the sparkle and shine of the mineral. Since they are only composed of carbon, diamonds are considered allotropes which are different structures created from the same single chemical element.

Diamond cont.

Diamond’s chemical formula is simple and is represented by just a “C”, as it is made up of the element carbon. There are some other trace elements or impurities that account for less than 0.05% of a diamond’s chemical composition. These trace elements can sometimes influence the colour or the shape of the mineral as they can be found in kimberlite igneous rocks. Trace elements are also referred to as impurities and can add or reduce the value of prized minerals.

Diamond's Structure

One of the characteristics that make diamonds unique aside from their composition, is the arrangement of atoms in their chemical structure. Diamonds are made up of chains of carbon atoms sourced from the formation of volcanic rock miles below Earth’s surface. Carbon atoms stick together with covalent bonds forming tetrahedrons. Tetrahedrons build to form triangular prisms which is one of the strongest support shapes. This crystalline prism structure is the three- dimensional arrangement of atoms found in diamonds.

Fun Facts about Diamond...

  • The word diamond comes from a Greek word meaning unbreakable.
  • Diamond is the best known thermal conductor (heat transfer) among naturally occurring substances.
  • There is a diamond in outer space that is the same size of our moon.
  • Diamonds are the strongest substance on the planet, but other materials can still scratch them.
  • Diamonds are the only gems made of one element.
  • Diamonds are the only gems made of one element.
