WebThis video covers how atoms gain or lose electrons to form ions, why they bother, and how to tell which ion they'll become. Based on AQA course, but suitable... WebIons with a negative charge are called anions. Many normal substances exist in the body as ions. Common examples include sodium, potassium, calcium, chloride, and bicarbonate. These substances are known as electrolytes. Ions can be created using radiation such as x-rays. Ionizing radiation is often used to diagnose or treat a medical condition.
WebIonic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.. The concept can be extended to solvated ions in liquid … WebAtoms, isotopes and ions - AQA Atoms are made up of protons, neutrons and electrons. Change the number of neutrons in an atom and it becomes an isotope, change the number of electrons, it becomes ...
