Explanation:
Atomic Number 11 Atomic Number 11 is belong to element of Sodium. Chemical symbol for Sodium is Na. Number of protons in Sodium is 11. Atomic weight of Sodium is 8 u or g/mol. Atomic Number of Sodium Atomic Number of Sodium is 11. Chemical symbol for Sodium is Na. Number of protons in Sodium is 11. Atomic weight of Sodium is 8 u or g/mol. Melting point of Sodium is 97,8 °C and its the boiling point is 892 °C.
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 Vpn shield for mac.
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

Sodium is one of the oldest known chemical elements since it is essential for human life. It is consumed by all of us in the form of salt we use for cooking many types of foods, but is a bit dangerous for human body in high amounts (causes high blood pressure). Sodium is a soft metal and is the 6th most common chemical element on our planet. Sodium is a reactive element, especially with water and other chemical compounds, that is why it can not be found in nature as metal. The number of common sodium compounds is quite large (with sodium chloride being the most common of those), and they are used in plenty of industries, including toothpaste production, producing soaps, foodstuffs, as well as industrial and nuclear chemistry, and many others.
