what equals Na when you add e to it
When you add an "e" to Na, it becomes "NaN" which stands for "Not a Number" in computing.
When you add the chemical symbol "e" (which represents electrons) to the element symbol "Na," it means you are adding one electron to the atom of sodium (Na). The resulting entity is called a sodium ion (Na+). In this form, sodium has a positive charge and has lost one electron.
To determine what equals "Na" when you add "e" to it, we need to clarify what "Na" represents in this context.
If "Na" refers to the chemical symbol for sodium (Na), and "e" represents an electron, then adding an electron to a sodium atom would result in the formation of a negatively charged ion called a sodium ion (Na+).
However, if "Na" and "e" are not referring to sodium and an electron respectively, please provide more information for further clarification.
