words only definitions & notes
  1. electronegative
    having a negative charge
    When a highly electropositive metal is combined with a highly electronegative nonmetal, the extra electrons from the metal atoms are transferred to the electron-deficient nonmetal atoms.
  2. electronegativity
    (chemistry) the tendency of an atom or radical to attract electrons in the formation of an ionic bond
    This tendency is known as electronegativity.
  3. electron
    an elementary particle with negative charge
    An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
  4. ion
    a particle that is electrically charged positive or negative
    An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
  5. electron shell
    a grouping of electrons surrounding the nucleus of an atom
    Formation
    Formation of monatomic ions

    Monatomic ions are formed by the addition of electrons to the valence shell of the atom, which is the outer-most electron shell in an atom, or the losing of electrons from this shell.
  6. proton
    a stable particle with positive charge
    An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
  7. noble gas
    any of the chemically inert gaseous elements of the helium group in the periodic table
    The most common type of ionic bonding is seen in compounds of metals and nonmetals (except noble gases, which rarely form chemical compounds).
  8. bonding
    the act of fastening firmly together
    Ionization potential
    * 3 Ionic bonding
    * 4 Plasma
    * 5 Applications
    * 6 Common ions
    * 7 See also
    * 8 References

    Notation

    When writing the chemical formula for an ion, its net charge is written as a superscript "+" or "−" (depending on if the ion is positive + or negative −) following a number indicating the difference between the number of protons and the number of electrons.
  9. sodium
    a silvery soft waxy metallic element of the alkali metal group; occurs abundantly in natural compounds (especially in salt water); burns with a yellow flame and reacts violently in water; occurs in sea water and in the mineral halite (rock salt)
    For example, the sodium cation is written as Na+, the "+" indicating that it has one fewer electron than it has protons.
