Qubit (game show) lustrous metal is the seventy-fourth element on the periodic table?" If the contestant answers incorrectly or passes, the host reads a clue such as: "Its chemical symbol is W, which stands for" Wolfram, "the German name of this element." If the contestant still answers incorrectly or passes, the host reads two choices, such as: "Is it platinum or tungsten?" Tungsten is the correct answer. The other answer is changed if necessary so it is not an answer already tried by the contestant. If the constant still answers incorrectly at this point, a 10-second time penalty is applied. The contestant with
Melting point the same space. The Lindemann criterion states that melting is expected when the vibration root mean square amplitude exceeds a threshold value. Assuming that all atoms in a crystal vibrate with the same frequency "ν", the average thermal energy can be estimated using the equipartition theorem as where "m" is the atomic mass, "ν" is the frequency, "u" is the average vibration amplitude, "k" is the Boltzmann constant, and "T" is the absolute temperature. If the threshold value of "u" is "ca" where "c" is the Lindemann constant and "a" is the atomic spacing, then the melting point is estimated
