         step  one;  calculate  mass
Mass=density   x volume
    1ml=1cm^3
   13.69g/cm^3  x  17  cm^3=232.73g

  step  2;  calculate  the   number of  moles  of   mercury
(232.73g/200.59g/mol)(molar  mass  of mercury=  1.1602moles
  
by  use   of  avogdros  law
1moles =6.023E23  atoms
what about  1.1602moles
=1.1602 x 6.023E23=  6.988E23atoms

On the basis of electronegativity, which of these pairs of elements is most likely to form monatomic ions?
mixer [17]

Answer is: Cl and Na.

sodium and chlorine are in third period and they have very different properties. Sodium is solid metal and chlorine is gaseous nonmetal.

They form compound NaCl (Sodium chloride), because sodium lost one valence electron and form cation Na⁺, chlorine gain one electron and form anion Cl⁻.

Electron configuration of sodium atom: ₁₁Na 1s² 2s² 2p⁶ 3s¹.

Electron configuration of chlorine atom: ₁₇Cl 1s² 2s² 2p⁶ 3s² 3p⁵.

Other examples are metal-metal pairs and they do not form cation and anion.
