For example, the atomic number of sodium is 11. The element also has an atomic number of 11, meaning that it has 11 electrons and 11 protons. The atomic number of sodium is 11. How long will the footprints on the moon last? The Mass Number of an element is equal to the protons added to the neutrons.. Since, atomic number of sodium is 11. Copyright © 2020 Multiply Media, LLC. Only sodium atom react vigorously with water whereas sodium ion … The total number of protons and neutrons in an atom is called its nucleon number. Neutron Number and Mass Number of Sodium Mass numbers of typical isotopes of Sodium are 23. Find the cheap Sodium Number Of Protons, Find the best Sodium Number Of Protons deals, Sourcing the right Sodium Number Of Protons supplier can be time-consuming and difficult. The first and second ionization energies are 495.8 kJ/mol and 4562 kJ/mol), respectively. 0 0. Each atom also has 11 protons and 11 electrons, giving sodium an atomic number of 11. A. neutrons and electrons B. protons and electrons C. protons and neutrons D. neutrons and atoms . Number of Neutrons: 12. 1 Valence Electron. Because negative and positive charges attract, sodium and chlorine ions stick together, creating an ionic bond.
