Jan 31, 2013 · If in the process of ionic bonding, would Nitrogen be an cation or an anion? 3. Lithium has a charge of +1 and Nitrogen has a charge of -3. What would be the name of ...The radius for a cation is smaller than the parent atom (Al), due to the lost electrons; the radius for an anion is larger than the parent (S), due to the gained electrons. Cations with larger charges are smaller than cations with smaller charges (e.g., V 2+ has an ionic radius of 79 pm, while that of V 3+ is 64 pm). For example, if a molecule of nitrogen loses an electron, it becomes a cation with a charge of +1. Ionization energy Electrons in an atom are attracted to the atomic nucleus by electrical forces. Carbon disulfide cation: 1: NO 2-Nitrogen dioxide anion-1: NO 2 + Nitrogen dioxide cation: 1: PO 2-Phosphorus dioxide anion-1: PO 2 + Phosphorus dioxide cation: 1: O ...
The cation is always named first and the anion second. A simple cation (one atom) takes its name from the name of the element. Ex. Na+ is called sodium. A simple anion (one atom) is named by taking the first part of the element name (the root) and adding -ide. Ex. Cl- is called chloride. In general, metal atoms tend to lose electrons to form cations, whereas nonmetal atoms tend to gain electrons to form anions. SAMPLE EXERCISE 2.7 Give the chemical symbols, including mass numbers, for the following ions: (a) The ion with 22 protons, 26 neutrons, and 19 electrons; (b) the ion of sulfur that has 16 neutrons and 18 electrons.
