Gold exist as native element, with a specific color, is not reactive - as a consequence it is simply to be identified. Sodium is very reactive, form many minerals and methods to be separated doesn't exist before 1 800.
Nothing until it's extracted from the earth
The molecule Sodium Chloride (NaCl), is the result of sodium (Na), and chlorine (Cl), reacting with each other until the electrons are balanced. This chemical change causes these two elements to create, what you would know as, table salt.

It was discovered by Sir Humphrey Davy ACTUALLY .... it was discovered by Carl Scheele in 1774 but not extracted until 1808 because Barium is a coumpound of other elements when Mr. Scheele discovered it .. it wasn totally pure until Mr. Davy extracted it from the other compounds to make it a pure element!
As sodium chloride is heated, the vibrations of the individual sodium chloride molecules increase, forcing adjacent sodium chloride molecules to move away until they have enough room to vibrate. Once the temperature increases to 801 °C (1,474 °F), the molecules are so far apart that they can't hold together anymore. So, they fall apart and act as a liquid. Viola, molten sodium chloride.
Sodium is a very highly reactive metal, sodium has to be extracted by electrolysis from its rock salt, the process of electrolysis had to be invented.
It didn't. The town was complete buried and lost to time from the eruption of Vesuvius for about two thousand years until uncovered in the 1800s.
The main extraction method for sodium is electrolysis. This extraction method was not discovered until 1807.
Italian was the leading style of opera in Europe until the mid 1800s.
No, not until about the 1920's
that they may not speak until spoken to.
Take out one letter, using a random number. Then replace the string with the new string, without the extracted letter. Repeat, until the remaining string has a length of zero. The extracted letters get added to a new string.Take out one letter, using a random number. Then replace the string with the new string, without the extracted letter.

The process of electrolysis had to be invented before sodium could be separated. That process was not invented until 1807.
In the 1800s throught 1900s and until now
The prisoners of Alcatraz had no complaints in the 1800s because the prison was not established until 1934.
