Chapter 6 Chemistry
Show Answers:

  1. Ion
    • A positively or negatively charged group of atoms
    • i.e.- When else atom loses electrons to look like the nearest noble gas, it becomes a positively charged ion
    • This is shown in the figure below
  2. Chemical bond
    • A chemical link between two atoms, which holds the atoms together¬†
    • i.e.- ionic bond, convalent bond
  3. Ionic bond
    • A chemical bond that froms between oppositely charged ions
    • This forms between two ions to create a neutral compound
  4. Ionic compound
    • A compound made of oppositely charged ions
    • When one or more electrons are transfered from one atom to another. This is to create a full set of valence electrons.
  5. Molecular compound
    • A compound formed when atoms of two or more different elements share electrons
    • Formed when atpairs hare a pair of electrons to form a covalent bond
  6. Covalent bond
    • A chemical bond in which two atoms share one or more pairs of electrons
    • An analogy for a convalent bond is a tug of war game because two teams are joined by one mutual rope
  7. Molecule
    • The smallest discrete particle of a molecular compound; has one or more shared pairs of electrons in one or more convalent bonds
