Web4 sep. 2024 · Because ions are electrically charged, they are affected by magnetic fields. Monatomic vs. Polyatomic Ions If an ion consists of a single atom, it is called a monatomic ion. An example is the hydrogen ion, H +. By contrast, polyatomic ions, also called molecular ions, consist of two or more atoms. WebBecause the concentration of Na + is higher outside the cell than inside the cell by a factor of 10, ions will rush into the cell that are driven largely by the concentration gradient. Because sodium is a positively charged ion, it will change the relative voltage immediately inside the cell relative to immediately outside. ponds spotless glow
