Sodium Mass Number. Sciences, Culinary Arts and Personal What is a common name for sodium bicarbonate? Number of neutrons in sodium nucleus is 12. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. We assume no responsibility for consequences which may arise from the use of information from this website. Sodium (Na) Sodium has an atomic number of 11 and a mass of about 23g. 0 0. ricchetti. 23g per mol (23 amu … 1) You may use almost everything for non-commercial and educational use.

Mass number is protons plus neutrons and can be different for different isotopes. 2) You may not distribute or commercially exploit the content, especially on another website. 0 0. Since sodium has 11 protons, the number of neutrons is given by mass number – number of protons (23 - 11) = 12 neutrons. Source(s): https://shrink.im/a9CF8. 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. All rights reserved. You can find this number by looking on the Periodic Table. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. There are 21 recognized isotopes of sodium (11 Na), ranging from 18 Na to 39 Na and two isomers (22m Na and 24m Na). You can find this number by looking on the Periodic Table. Religious, moral and philosophical studies. aprox. 23 Na is the only stable (and the only primordial) isotope. This website does not use any proprietary data. Lv 4. 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. Become a Study.com member to unlock this In some periodic tables there is a dark zigzag line that separates the metal elements from the non-metal elements. Its atomic number is 11 and symbol is 'Na'. The mass number of an element tells us the number of protons AND neutrons in an atom (i.e. For 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. There are 2 isotopes of sodium, Na-22 and Na-23. The mass number is provided for each of the elements, and... Our experts can answer your tough homework and study questions. One atomic mass unit is equal to 1.66 x 10-24 grams. Density is defined as the mass per unit volume. 0 0. 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.
