I was thinking,
\(Na\longrightarrow H\, +\, positive\,\,temp.\,\, partilces\)
and then
\( Na+H_{ 2 }O+H\longrightarrow NaOH +H_2\)
but they are at odds with basic ionic chemical equations. The idea is that more temperature particles in hydrogen (\(H\)) makes sodium (\(Na\)); as one move down a group in the periodic table. One way of releasing those positive temperature particles in sodium (Na) is to react it with water (\(H_2O\)). In the process, the metal is transmuted up the group in the period table, into hydrogen (\(H\)). Lithium (\(Li\)), is found in trace amount at the end of the reaction.
\(2Na+H_{ 2 }O\longrightarrow NaOH+H_2\, +\, positive\, \, temp.\, \, partilces\)
which combines the previous two equations. This might explain the mass discrepancy observed when the metal reacts with water.
Sodium is a positive temperature particle source.
