WebIons: Ions are atoms that have lost or gained electrons. In doing so, they become charged due to an imbalance between the number of negatively charged electrons and positively charged protons in the ions. Ions that are positive are called cations, while negative ions are called anions. Answer and Explanation: 1 WebQ2. Two chambers are separated by an impermeable membrane with an ion channel permeable only to X; an anion. The left side of the chamber has four double-charged cations, C+, and four single-charged anions, X : The right side has four uncharged ions, Z∘, and four single-charged anions, X : Which way will the X-ion move once the channel opens? coach tours in scotland 2023
