  • What is an ion?
    An ion is an atom or molecule with a net electrical charge due to the gain or loss of electrons.
  • How do anions form?
    Anions form when an atom gains one or more negatively charged electrons, resulting in a net negative charge.
  • How do cations form?
    Cations form when an atom loses one or more negatively charged electrons, resulting in a net positive charge.
  • What is the main difference between anions and cations?
    Anions are negatively charged ions, while cations are positively charged ions.
  • What type of bond forms between cations and anions?
    An ionic bond forms between cations and anions due to electrical attraction between their opposite charges.
  • Do ionic bonds involve sharing or transferring electrons?
    Ionic bonds involve a complete transfer of electrons, not sharing.
  • Why do atoms undergo ionic bonding?
    Atoms undergo ionic bonding to achieve full valence shells, which increases their stability.
  • What happens to the valence shells of atoms involved in ionic bonding?
    The valence shells of both atoms become full after the transfer of electrons in ionic bonding.
  • What is the charge of a sodium ion after it loses an electron?
    After losing an electron, a sodium ion has a positive charge and is called a cation.
  • What is the charge of a chloride ion after it gains an electron?
    After gaining an electron, a chloride ion has a negative charge and is called an anion.
  • What causes the attraction in an ionic bond?
    The attraction in an ionic bond is caused by the opposite charges of the cation and anion.
  • What is a common example of an ionic compound?
    Sodium chloride (NaCl), or table salt, is a common example of an ionic compound.
  • What happens to a neutral hydrogen atom if it gains an electron?
    If a neutral hydrogen atom gains an electron, it becomes a negatively charged anion.
  • What happens to a neutral hydrogen atom if it loses its electron?
    If a neutral hydrogen atom loses its electron, it becomes a positively charged cation.
  • Why does chlorine take an electron from sodium in the formation of NaCl?
    Chlorine is much more electronegative than sodium, so it pulls the electron away, resulting in a complete transfer.
