amino acid methionine is depicted in the picture. C5H11NO2S is the molecular formula for methionine. Calculate the mass of a single methionine molecule, given that all of the atoms are in their most frequent isotopic forms (12C, 1H, 14N, 16O, 32S
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.
