Since the atomic mass of Sodium is 23, we can also write it as 23 g/mol.Therefore, we conclude that Option B is the correct answer.Additional Information:The atomic number of a chemical element is the number of protons found in the nucleus of every atom...
1/12 the mass of a neutral atom of 12C, equal to 931.5 MeV. Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the number of protons Z and...
What is the mass number of an atom? If the atomic mass of an element is x, what is the mass in grams of 6.02 X 10^{23} atoms of the element? What is the number of protons in sodium? What is the definition of atomic weight in chemistry?
Examples of Atomic Number The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. Atomic number = Number of protons For example, in a sodium atom, there are 11 electrons and 11 protons. Thus ...

Figure 2.1.Mass spectrum of the pentafluoropropionyl (A) and carbethoxyhexafluorobutyryl (B) derivatives ofd-methamphetamine. An ion may be positively charged, in which case the number of electrons in the ion is less than the sum of the number of protons in all nuclei of the ion, or negat...
An icosahedron of this giant rare-gas atom, (Na 2 ) 13 , is expected to be stable and corresponds well to the non-shell-closing magic number, 26, in the mass spectrum of sodium clusters. Another example is a giant alkali-metal atom, Na 19 , which has a spherical core and one s-...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
