6. Iron(II) ion salts, such as FESO, · 7H,0, react with the organic compound ortho-phenanthromne phen) to form red coordination compounds with formulas such as Fe(phen),,SO4. Such compounds have an analytical wavelength of 510 nm. (1) A standard solution containing Fe(phen), SO, was made by dissolving 0.0139 g of FeSO4 · 7H;O, with a molar mass of 278.05 g mol1 in 500.0 mL of water containing excess phen. The solution has a %T of 36.5% at 510 nm. A 500.0-mL solution with unknown Fe(phen),,SO4 concentration has a %T of 64.3% at 510 nm. What is the molar concentration of Fe(phen),,SO4 in the unknown solution?

Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
