Sodium atom diagram
The Sodium Zeeman Effect The sodium spectrum is dominated by the bright doublet known as the Sodium D-lines at 588.9950 and 589.5924 nanometers. From the energy level diagram it can be seen that
these lines are emitted in a transition from the 3p to the 3s levels. Sodium is a chemical element with symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal.Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a
positively charged ion—the Na + cation.Its only stable isotope is 23 Na. Charge It! Electrons are the negatively charged particles of atom.Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The mass of an electron is almost 1,000 times smaller than the mass of a proton. Hydrogen Energy Level Plot The basic structure of the hydrogen energy levels can be calculated from the Schrodinger equation. The energy levels agree with the earlier Bohr model, and agree with experiment within a small fraction of an electron volt. Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, commonly known as salt (though sea salt also contains other chemical salts), is an ionic compound with the
chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible www.chemactive.com GCSE CHEMISTRY ATOMIC STRUCTURE & BONDING High Demand Questions QUESTIONSHEET 2 (a) There are eleven electrons in a sodium atom.

Simon Fraser University Sep 25, 2012 · My question is: Why the energy levels for sodium are different from those for hydrogen even though sodium is described as a
"hydrogen-like atom"? Here I have posted the energy diagrams for sodium, and hydrogen. So, I have noted that sodium has … The modern chemical bond. While still in college, a young chemist by the name of Linus Pauling familiarized himself
with Lewis’s work and began to consider how it might be interpreted within the context of the newly developed field of quantum mechanics.The theory of quantum mechanics, developed in the first half of the 20th century, had redefined our modern understanding of the atom and so Engage Introduce students to Lewis dot structures. Tell students that one popular method of representing atoms is through Lewis dot diagrams. In a dot diagram, only the symbol for the element and the electrons in its outermost energy level (valence electrons) are shown.
