Find the mass of one atom by:
8.33 x 10^{-16} / 2.5 x 10^{6} = 3.32 x 10^{-22} g
Convert it into amu.
1 g = 6.022 x 10^{23} amu
so, 3.32 x 10^{-22} x 6.022 x 10^{23} = 200.6 amu
Now look at the periodic table and search for 200.6 amu element.
The element is Mercury (Hg)

Answer:
The coordination number is 4.
Explanation:
- Square planar clusters can be either cis or trans, as they form 180 and 90-degree bond angles. Therefore, a pair of ions may be adjacent (cis) to one another and immediately across (trans) from one another.
- A square planar molecule could never be simultaneously cis and trans, so because several coordinators are 4.
- Since linear complexes have only an angle of a bond of 180 degrees, they can not have cis or trans-isomers. In the coordination complex, there is only yet another way possible of bonding the two binding sites to the steel.
To balance a chemical reaction, we need to remember that the number of each atom in the reactant and the product side of the equation should be equal. So, from the reaction <span>P4(s) + Cl2(g) = PCl3(l), there are 4 P atoms in the reactant, the P atoms in the prodcut side should be 4 as well. We balance as follows:
</span> P4(s) + 6Cl2(g) = 4PCl3(l)
<span>
Therefore, the coefficient of the PCl3 should be 4.
