allegedly recovered from the legendary king solomon’s mines, the uncut, rough stone was acquired in 1544 by the scandalous de luca family. gifted as part of a dowry in 1612, the fate of the diamond, along with several other high profile gems, were unknown after the franco-spanish war of 1635, before it mysteriously reappeared over three centuries later. sold last year to the moretti brothers jewellers for just over £22 million, neither time nor conflict have dimmed its brilliance. indeed, the twin eighty-year-old brothers suggests that the value of the now cut and polished 90 carat diamond has already increased by at least 50%. it will be on display for four weeks only.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
