Iron(II) sulfide has a primitive cubic unit cell with sulfide ions at the lattice points.

masya89 [10]

We have that the the density of FeS is mathematically given as

$\phi=2.56h/cm^3$

From the question we are told

Iron(II) sulfide has a primitive <em>cubic</em> unit cell with <em>sulfide</em> ions at the <em>lattice points.</em>

The ionic radii of iron(II) ions and sulfide ions are 88 pm and 184 pm, respectively.

What is the density of FeS (in g/cm3)?

<h3>Density</h3>

Generally the equation for the Velocity is mathematically given as

$V_c=a^3=(2\pi Fe^{2+}+2\pi S^{2-})^3\\\\Therefore\\\\V=a^3(2\pi*0.088+2\pi 0.184)^3\\\\V=16.98*10^{-23}\\\\Therefore\\\\\phi=n\frac{PFeion+PSion}{VNa}\\\\\phi=3*\frac{55.85+32}{16.9*10^{-23}*6.023*10^{23}}$

$\phi=2.56h/cm^3$

$\phi=2.56h/cm^3$

<h3> <u>ANSWER</u> </h3>

4. O²-

<h3><u>EXPLANATION</u> </h3>

O²- has 16 electrons while Ne has 18 electrons. O²- is a molecule that has one electron added to each atom, meaning that there are two extra electrons which makes O²- the same electron configuration as of Ne atom.
