We know that the atomic number of sodium is 11. It is an intensive property, which is mathematically defined as mass divided by volume: In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. The chemical symbol for Sodium is Na.. Atomic Mass of Sodium. 23 Na is the only stable (and the only primordial) isotope. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol. For any element number of neutrons = mass number - atomic number = 23 - 11 = 12. Source(s): https://shrink.im/a9CF8. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. Sign in .
This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. Since sodium has 11 protons, the number of neutrons is given by mass number – number of protons (23 - 11) = 12 neutrons. How many atoms are in sodium bicarbonate? Read about our approach to external linking. Sodium's mass number is 22.99. George S. Lv 4. 4 years ago.
There are 2 isotopes of sodium, Na-22 and Na-23. For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63 and an isotopic mass in its nuclear ground state is 62.91367 u. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure.
For 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. There are 21 recognized isotopes of sodium (11 Na), ranging from 18 Na to 39 Na and two isomers (22m Na and 24m Na). 1 decade ago. How do you think about the answers? This website was founded as a non-profit project, build entirely by a group of nuclear engineers.
The standard SI unit is kilograms per cubic meter (kg/m3). is given at the top left of the element's symbol, for example, sodium has a mass number of 23. 1 decade ago. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure. There are two reasons for the difference between mass number and isotopic mass, known as the mass defect: Typical densities of various substances at atmospheric pressure. in an atom (i.e. Our Website follows all legal requirements to protect your privacy.
