Find the atomic number (Z) and mass number (A). The atomic mass of sodium depends on the isotope of sodium that you are studying. You can find the atomic mass of any element by looking on the periodic table of the elements. 2000 times smaller than protons so its mass is taken as negligible: Atomic mass of sodium(na)=no. A. Sodium is present in fair abundance in the sun and stars. Sodium nitrite, benzoate, monosodium glutamate (MSG) are other food additives. Then, gram atomic mass of Fe = 56 g. Now, 56 g of Fe contains = 6.022 x 10 23 g number of atoms. This means one hydrogen atom is 1 times heavier than 1/12 th of the carbon atom. Then, gram atomic mass of Na = 23 g. Now, 23 g of Na contains = 6.022 x 1023 g number of atoms. The molecular mass of CH 4 – atomic mass of C + 4 x atomic mass of H = 12 + ( 4 x 1)u = 16u It is placed in group 1 of periodic table as it has a single electron in its outer most shell that it readily donates, creating a positively charged ion, the Na+ cation. Predict the atomic mass of sodium. Then the molecular mass of NaOH is :22.99+16+1=39.99u Lithium, sodium and potassium form a Dobereiner's triad. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28 (2).Sodium has two radioactive cosmogenic isotopes (22 Na, half-life = 2.605 years; and 24 Na, half-life ≈ 15 hours). Melting point of Sodium is 97,8 °C and its the boiling point is 892 °C. chemistry. The D lines of sodium are among the most prominent in the solar spectrum. Choose your element. 22.9898 u (unified atomic mass units) 0 0. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. Thus, 100 g of Na contains = 6.022 x 1023 / (23 x 100 number of atoms) 100 g of Na contains = 2.6182 x 1024 number of atoms. Gram atomic mass is the mass, in grams, of one mole of atoms in a monoatomic chemical element.
