The molar absorption coefficient of a substance dissolved in water is known to be 855 dm3mol-1cm-1 at 270 nm. To determine the rate of decomposition of this substance, a solution with a concentration of 3.25 mmol dm-3 was prepared. Calculate the percentage reduction in intensity when light of that wavelength passes through 2.5 mm of this solution. Ans: 1.6%
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.
