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.
An ionic bond is a bond between ions with opposite charges. Cations (positively charged ions) cannot exist without anions (negatively charged ions). An electron released by an atom to from a cation must be accepted by another atom to form an anion. Cations and anions are formed in many chemical reactions by the transfer of one or more electrons from one element to another. Ionic bonds are formed by a strong attraction between positive and negative ions. Characteristics of Ionic compounds. Some important characteristics of ionic compounds are as follows. 1. Ionic compounds are hard and rigid due to strong forces of attraction between the oppositely charged ions.
