Definition: a rare radioactive gas belonging to the noble gas series.
Atomic Mass - (222)g.mol^-1
Density - 9.96*10^-3g.cm^3 at 20 degree C
Melting/Boiling point - (-71) degree C (-62) degrees C
Ionic Radius - Unknown (The radius exhibited by an ion in an ionic crystal where the ions are packed together to a
point where their outermost electronic orbitals are in contact with each other.)
Isotopes - 7
Electronic Configuration - [Xe] 4f^14 5d^10 6s^2 6p^6 (How you figure this out is, That Xe, is a Noble gas just as Radon, but you can not have a Noble Gas stand by itself. So you must to the [Xe] in the sequence and then count from there. Here is the Sequence { 1s^2 2s^2 2p^6 | [Ne] | 3s^2 3p^6 | [Ar] | 4s^2 3d^10 4p^6 | [Kr] | 5s^2 4d^10 5p^6 | [Xe] | 6s^2 4f^14 5d^10 6p^6 | [Rn] | 7s^2 5f^14 6d^10 } Each noble Gas is placed where the exponent is a 6)
Chemical Series - Noble gas, Period 6 element, Nonmetal
Ionization Energy - 1037 kJ mol-1 1930 kJ mol-1 2890 kJ mol-1 [the minimum amount of energy required to remove an electron (to infinity) from the atom or molecule in the gaseous state.]

Atomic Radius - 134 (a chemical element is a measure of the size of its atoms)
Electronegativity - 2.2 (a measure of the tendency of an atom to attract a bonding pair of electrons) Electron affinity - Was not Found [the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion.] |
