Substance-Related and Addictive Disorders In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the revised chapter of âSubstance-Related and Addictive Disordersâ includes substantive changes to the disorders grouped there plus changes to the criteria of certain conditions.his new term and its loca-tion in the new manual reflect research findings that gambling disorder is similar to substance-related disorders in clinical expression, brain origin, comorbidity, physiology, and treatment.
Net Ionic Equation Definition. The net ionic equation is a chemical equation for a reaction which lists only those species participating in the reaction. The net ionic equation is commonly used in acid-base neutralization reactions, double displacement reactions, and redox reactions.
IONIC RADIUS. Ions are formed when the neutral atoms lose or gain electrons. A positive ion or cation is formed by the loss of one or more electrons by the neutral atom whereas a negative ion or anion is formed by the gain of one or more electrons by the atom.The term ionic radii refers to the size of the ions in the ionic crystals.The ionic radius of an ion may vary from crystal to crystal because of change in surrounding ions. The equilibrium distance between the nuclei of the two adjacent ions can be determined by X-ray analysis of ionic crystals.he term ionic radii refers to the size of the ions in the ionic crystals.
