How many protons, neutrons, and electrons are in a neutral atom of sodium?
Sodium Sodium is a chemical element with symbol Na and atomic number 11. Classified as a n alkali metal, Sodium is a solid at room temperature.
1 Answer
Explanation:
- Sodium (atomic number 11, symbol Na) is a metal and a chemical element that was discovered in 1807 by the Cornish inventor and chemist Humphry Davy. It occurs in sodium salts and minerals, including rock salt, sodalite, and feldspars.
- Atomic Number of Sodium. Sodium is a chemical element with atomic number 11 which means.
The subatomic particles (protons, neutrons and electrons) can be determined using some basic information from the periodic table.
The Atomic Number of an element is always equal to the number of protons. The Mass Number of an element is equal to the protons added to the neutrons.
The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23.
Therefore
An atomic number of 11 means this atom will have 11 protons.
A mass number of 23 means 23 - 11 this atom will have 12 neutrons.
Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons.
Protons 11
Neutrons 12
Electrons 11
