The cyanide ion is extremely toxic because it interferes with the functioning of cytochrome oxidase (Cyt-Fe³+), an iron-containing enzyme that is essential for cell respiration. The cyanide ion reacts with the iron of the enzyme to form a very stable covalent complex as shown below, leading to enzyme inactivation. What type of inhibitor is the cyanide ion?

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.
