The atomic number of Sodium = 11,Number of neutrons in the nucleus of the Sodium ion = 12 The atomic mass of Sodium $=11+12=23$ Hence, 1 mole of Sodium weighs 23 grams.We know,Since the atomic mass of Sodium is 23, we can also write it as 23...
Science Chemistry Mass number What is the atomic number of sodium?Question:What is the atomic number of sodium?Atomic Structure:Atoms are the smallest particles that still maintain the properties of an element. Atoms have a core called a nucleus made of protons and neutrons. They also have a...
What is the relative atomic mass of sodium? Sodium: On the periodic table of elements, the chemical element sodium is shown by the symbol Na. Sodium has an atomic number of 11, which means it has 11 protons. Key Terms Element: An element is a chemical substance that cannot be broken do...
75.53 of these atoms each have a mass of 35 atomic mass units (AMU), and 24.47 atoms each have a mass of 37 AMU. The word mole has been adopted to represent the Avagadro number of atoms of an element, that is, the relative atomic mass of an element. Thus, one mole of sodium ...
counting whole objects (protons, neutrons, and electrons). The sum of the mass number and the atomic number for an atom (A-Z) corresponds to the total number of subatomic particles present in the atom. The mass number reports the mass of the atom’s nucleus in atomic mass units (amu)....
Mass number \(=\) Number of protons \(+\) Number of neutrons For example, one atom of a sodium element contains \(12\) neutrons and \(11\) protons, so the mass number of sodium is \(11 + 12 = 23.\) Similarly, a carbon atom has \(6\) protons and \(6\) neutrons, so the...
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 neutrons N. Isobar Member of a set of nuclides of the same at...
