The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. Explain. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Atomic number (number of protons in the nucleus): 11 2. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation. The electronegativity of Sodium is: χ = 0.93. Atomic weight of Sodium is 22.98976928 u or g/mol. The chemical symbol for Sodium is Na . Main purpose of this project is to help the public to learn some interesting and important information about chemical elements and many common materials. The atomic mass is carried by the atomic nucleus, which occupies only about 10-12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. At room temperature Sodium is soft, silvery-white metal which can be easily cut with a knife. Sodium. A Sodium atom, for example, requires the following ionization energy to remove the outermost electron. Melting point: 208.04 degrees Fahrenheit (97.80 degrees Celsius) 7. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Sodium, a chemical element with symbol Na, is one of the highly reactive alkali metals of group 1 with atomic number 11 in the periodic table. Therefore we can say that sodium has eleven protons. Every sodium atom has 11 protons and 11 electrons. 23 Na is the only stable (and the only primordial) isotope. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. The Cookies Statement is part of our Privacy Policy.
