The expected mass of sodium is 23.18402 that can be calculated taking number of protons and neutrons into consideration.
Sodium atoms haven't any charge, sodium has 11 protons in its nucleus and 11 electrons orbiting it, simply as it's miles for any detail withinside the elemental state. This makes it electrically neutral.
The number of protons of sodium is 11.
The number of neutrons of sodium is 23-11=12.
Thus, the expected mass of sodium is expressed as follows:
m= 11*m 1H1+12*3 1n0
=11*1.007276 amu +12*1.008665 amu
=23.184016 amu
=23.18402 amu
Therefore, the expected mass of sodium is 23.18402.
