Common anion examples

• What are anions?

  Ions that gain electrons and become negatively charged
• How are anions formed?

  When atoms receive electrons
• What happens to the charge of an anion as it gains more electrons?

  The negative charge increases with more electrons
• Why do anions have a negative charge?

  They have more electrons than protons
• What are polyatomic anions?

  Negatively charged ions formed from multiple atoms
• What are the naming conventions for anions?

  • Monatomic anions end with "-ide"
  • Polyatomic anions may end with "-ate" or "-ite"
  • "-ate" indicates more oxygen, "-ite" indicates less oxygen
• What is the naming convention for polyatomic anions with oxygen?

  Use "-ate" for more oxygen, "-ite" for less
• What is the relationship between anions and cations in ionic compounds?

  Anions bond with cations to form compounds
• How do anions achieve stability?

  By completing their outer electron shells
• What creates a stable compound in ionic bonding?

  Attraction between oppositely charged ions
• What happens to the atom (neutral) to become an anion?

  The atom gains electrons
