key term - -ide

Definition

The suffix '-ide' is a common ending used in chemical nomenclature to denote a compound containing a specific element or group. It is typically used to name binary compounds, where the element or group represented by the '-ide' suffix is combined with another element.

5 Must Know Facts For Your Next Test

  1. The '-ide' suffix is used to name compounds where the element or group represented by the '-ide' is the more electronegative of the two elements.
  2. Compounds with the '-ide' suffix are typically ionic in nature, with the element or group represented by the '-ide' acting as the anion.
  3. The element or group represented by the '-ide' suffix is often a nonmetal, such as chloride (Cl-), oxide (O2-), or sulfide (S2-).
  4. The '-ide' suffix can also be used to name compounds containing polyatomic ions, such as carbonate (CO3^2-) or phosphate (PO4^3-).
  5. Naming compounds with the '-ide' suffix follows a specific set of rules, including the order of elements and the use of prefixes to indicate the number of atoms.

Review Questions

  • Explain the relationship between the '-ide' suffix and the electronegativity of the elements in a binary compound.
    • The '-ide' suffix is used to name binary compounds where the element or group represented by the '-ide' is the more electronegative of the two elements. This means that the element or group with the '-ide' suffix is the anion, which is the negatively charged ion formed when an atom gains one or more electrons. The more electropositive element, or cation, is the positively charged ion formed when an atom loses one or more electrons. The combination of the anion and cation results in an ionic compound.
  • Describe the typical ionic nature of compounds with the '-ide' suffix and the role of the '-ide' element or group.
    • Compounds with the '-ide' suffix are typically ionic in nature, with the element or group represented by the '-ide' acting as the anion. The anion is the more electronegative of the two elements, and it is attracted to the cation, or the more electropositive element, to form the ionic compound. The '-ide' element or group is often a nonmetal, such as chloride (Cl-), oxide (O2-), or sulfide (S2-), and it is responsible for the overall charge and chemical properties of the compound.
  • Analyze the rules and conventions for naming compounds using the '-ide' suffix, including the order of elements and the use of prefixes.
    • The naming of compounds with the '-ide' suffix follows a specific set of rules and conventions. The order of the elements is determined by the electronegativity difference, with the more electronegative element represented by the '-ide' suffix coming first. Prefixes are used to indicate the number of atoms of each element, such as mono- for one, di- for two, and so on. For example, the compound consisting of one sodium atom and one chlorine atom would be named sodium chloride (NaCl), while the compound with two chlorine atoms and one sulfur atom would be named disulfide (S2-). Understanding these naming rules is crucial for correctly identifying and communicating the composition of chemical compounds.
