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.

Chlorophyll absorbs photons strongly in two bands, one between 340 and 450 nm and the other between 650 and 680 nm. Chlorophyll collects and transfers the photon energy to fix CO2 into carbohydrate CH2O units according to CO2 + H2O → (CH2O) + O2 where the (CH2O) indicates one carbon unit of the carbohydrate. The average enthalpy change for the addition of a carbon unit to a carbohydrate is ΔH = 485 kJ/mol. What is the minimum number of 660 nm photons needed by chlorophyll to add a carbon unit to a carbohydrate? (Remember that there’s no such thing as a partial photon.) Please no copy paste from anywhere
