They all have the same number of protons (12).
The number of protons (the atomic number) is the same for all atoms and ions of Na.
However, atoms and ions have different numbers of electrons.
An <em>Na atom</em> has 11 electrons, but an <em>Na^(+) ion</em> has only 10 electrons.
Composer and performer of Old Occitan lyric poetryduring the High Middle Ages (1100–1350). Since the word troubadour is etymologically masculine, a female troubadour is usually called a trobairitz.
Answer:
A radical is a group of atoms behaving as a unit in a number of compounds where as an element is a species of atoms having the same number of protons in their atomic nuclei.
Explanation:
The net ionic equation of the reaction could be determined by cancelling out the like ions between both sides of the reaction. These ions are called spectator ions. They are called as such because they do not actively participate in the reaction. The spectator ions are Na+ and Cl-. When you cancel those, the equation would become letter D.
