The element below sodium with atomic number 11 is lithium. Lithium is a metal in the same alkali metal family as sodium.
The chemical symbol for the element of Sodium is Na and its atomic number is 11.
Sodium symbol: Na Atomic number: 11
The atomic number for sodium is 11, which means that sodium has 11 protons in its nucleus. This defines sodium as an element and determines its unique chemical properties. The atomic number also helps identify sodium's position on the periodic table.
The chemical symbol for the element sodium consists of a first capital letter and a second non capital letter: "Na". The atomic number of sodium is 11. (The term "first symbol" used in the question has no particular meaning of which I am aware.)
The atomic number is the number of protons in an atom of an element. For example, Sodium's atomic number is 11. This tells us that an atom of sodium has 11 protons in its nucleus. The interesting thing here is that every atom of sodium contains 11 protons. If an atom doesn't have 11 protons, it can't be an atom of sodium. Adding or removing protons from the nucleus of an atom creates a different element. For example, removing one proton from an atom of sodium creates an atom of neon.
