Atomic mass of sodium | Mass of Na

Sodium is a soft, silvery-white, highly reactive metal with the symbol Na. and atomic number 11. It’s delicate and highly reactive. Sodium belongs to the periodic table’s group 1 as an alkali metal. It has only one stable isotope, 23Na. Atomic mass of sodium is 23.

It’s a silver-white metal that’s highly reactive and soft. It is an alkali metal with a single electron on its outer shell and belongs to group 1 of the periodic table. Sodium is a chemical element used as a heat exchanger in some nuclear reactors and as a chemical industry reagent. On the other hand, sodium salts have more applications than metal. Sodium chloride is the most prevalent sodium compound (common salt). It’s used to flavor food and to de-ice roads in the winter.

Similarly, Soap is also made up of sodium salts of various fatty acids. The paper, glass, soap, textile, petroleum, chemical, and metal industries all rely on sodium compounds. On the other hand, Sodium is used in the human body to control blood pressure and volume. Your body also needs sodium for your muscles and nerves to work properly. It is the sixth most prevalent metal in the earth’s crust. Many of the sodium salts are extremely soluble. It is significant for both plants and animals. In some nuclear reactors, Sodium is also employed as a heat exchanger. It is a material with a low melting point due to its greyish-white colour being exposed to the air.

Sodium is an essential alkali metal in terms of commerce. The electrolysis of molten sodium chloride is used in the majority of sodium production operations. The element is used to make gasoline additives, polymers like nylon and synthetic rubber, medicines, and various metals like tantalum, titanium, and silicon. It is inexpensive and available in tank-car amounts. It’s also commonly utilized in heat exchangers and sodium-vapour lamps.

Atomic Mass and Atomic Number

Atomic Number is defined as the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table. We know that sodium has an atomic number of 11. This means sodium contains 11 protons and 11 electrons because it is neutral. The element’s mass number determines an atom’s number of protons AND neutrons.

An atom’s total number of neutrons and protons is called atomic mass. The atomic mass unit is Dalton. It is represented as Da and is the standard unit used to indicate the mass of an atom. The atomic mass of elements differs as it depends on the number of protons and neutrons in a particular element.

The atomic mass of Sodium is defined as the total number of protons and neutrons of an atom of a Sodium. In other words, it is also known as the Mass of Na. It is the A value in an element in the periodic table. Furthermore, the atomic mass of Sodium is calculated by adding it’s atomic number and the number of neutrons.

The relative atomic mass is a measure of how heavy atoms are. It is the ratio of the average mass per atom of an element from a given sample to 1/12 the mass of a carbon-12 atom.

The relative atomic mass in 1 mole of isotopes of sodium atoms is 23 g/mol.

I.e. Mass of Na= Atomic Number of Na + Number of Neutrons of Na, where

Atomic Number of Sodium=11

Number of Neutrons of Sodium= 12

Therefore, the Atomic mass of Sodium=23 g/mol

Furthermore, The number of protons, neutrons, electrons, atomic mass, and the atomic number of the Sodium is listed below:

  • Number of Protons of Na: 11
  • Number of Neutrons of Na: 12
  • Number of Electrons of Na: 10
  • Atomic Number of Na: 11
  • Atomic Mass of Na: 23

 

Difference between Atomic Mass of Sodium and its Atomic Number

Atomic Mass

Atomic Number

Atomic Mass is the average weight of an element form.

Atomic Number is the weight of the nucleus of an atom.

It is not symbolized as such.

It is written on the upper left hand corner of an elemental expression.

Atomic Mass relates to the average weight of an elemental form and hence it takes into consideration of the existence of isotopes and their abundance.

It does not take the existence does not take the existence of isotopes into consideration, as it relates to the weight of each atom separately.

It also deals with several decimal values as it is a weighted average.

It is a simplified number, usually without decimal places.

The Atomic Mass is helpful while performing specific calculations.

The Atomic Number is easier to use for general purposes. 

What is a Sodium Atom’s Maximum Mass Number?

The mass number contained in the bottom of the sodium atom is 22.989769 u 2 10-8 u.

Conclusion

As the mass of the sub-atomic particles are extremely small, it is quite inconvenient to express their mass in terms of gram, milligram, etc. The atomic unit is the unit of measuring extremely small masses. Hence, the mass of electron, proton and neutron is expressed in terms of atomic mass unit. 
Hence, At room temperature, sodium is lighter than water and can be sliced with a knife, but it becomes brittle at low temperatures. It efficiently conducts heat and electricity and has a strong photoelectric effect (emission of electrons when exposed to light). And to sum it up, the mass of na is 23.
