2.1.1 Formation of Ions

    Cards (28)

    • Ions are charged particles formed when atoms gain or lose electrons
    • Cations are negatively charged ions
      False
    • Anions are negatively charged ions formed when atoms gain electrons
    • Non-metals tend to form cations
      False
    • Ionic bonds form through the transfer of electrons from metal atoms to non-metal atoms
    • Metals form anions by losing electrons
      False
    • Steps in the formation of an ionic bond between sodium (Na) and chlorine (Cl)
      1️⃣ Sodium (Na) loses one electron to form Na+Na^{ + }
      2️⃣ Chlorine (Cl) gains one electron to form ClCl^{ - }
      3️⃣ Na+Na^{ + } and ClCl^{ - } ions attract each other to form NaCl
    • Match the atom type with its electron transfer and ion formed:
      Metal ↔️ Lose electrons, Cation
      Non-metal ↔️ Gain electrons, Anion
    • How do ionic bonds form?
      Electron transfer
    • Metals lose electrons to form cations
    • Non-metals gain electrons to form anions
    • What charge do cations have?
      Positive
    • What process do non-metals undergo to form anions?
      Gain electrons
    • When sodium (Na) loses an electron to chlorine (Cl), it forms Na^ +
    • The ionic bond formed between Na+Na^ + and ClCl^ - is Na+Na^ +Cl Cl^ -
    • What do ions achieve when they gain or lose electrons?
      Stable electron configuration
    • Match the ion type with its electron behavior:
      Cations ↔️ Lose electrons
      Anions ↔️ Gain electrons
    • Which type of ion loses electrons?
      Cations
    • Metals tend to form cations, while non-metals tend to form anions
    • Examples of cations include Na^ +
    • What is an example of an anion?
      Cl^ -
    • Cations are positively charged ions formed when atoms lose electrons
    • Anions are negatively charged ions formed when atoms gain electrons.
    • Ionic bonds result in atoms achieving a stable noble gas electron configuration.
    • When sodium reacts with chlorine, sodium loses one electron to form a cation
    • Ions achieve a stable electron configuration by resembling noble gases.
    • When sodium forms Na+Na^{ + }, its electron configuration changes to resemble that of neon
    • Common oxidation states for ions correspond to their charges
