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
Neptunium of manganese. Neptunium metal is similar to uranium in terms of physical workability. When exposed to air at normal temperatures, it forms a thin oxide layer. This reaction proceeds more rapidly as the temperature increases. Neptunium has been determined to melt at 639±3 °C: this low melting point, a property the metal shares with the neighboring element plutonium (which has melting point 639.4 °C), is due to the hybridization of the 5f and 6d orbitals and the formation of directional bonds in the metal. The boiling point of neptunium is not empirically known and the usually given value of 4174
