Electron configuration: What does 6mmol/l mean in blood

What does 6mmol/l mean in blood glucose ? What is the electron configuration of aluminium? The atomic number of an element is the total number of which particles? What is the electron configuration of an element with atomic number 8? The atomic number of an element is based on what? An element has an atomic number of 76. What is the number of protons and electrons in a neutral atom of the element? What is the atomic number of an element? Are you sure it is unstable.....? Certainly I can make metal oxides....Na_2O, and other alkali metal oxides, and I can make oxides of most other substances....oxygen is such a potent oxidant. And with iron and steel, all you have to do is erect the structure, and oxidation begins to take place. Of course in water, Na_2O, would give TWO equivs of hydroxide anion... Na_2O(s) + H_2O(l) rarr 2NaOH(aq)... When the subshell is half-filled, μS+L = μS. Besides that, when 1 4L(L + 1) is small compared to S(S + 1), μS+L ≈ μS is a good approximation. That is when We have a light atom (which occupies orbitals of low l, i.e. s or p orbitals). The atom is isolated (i.e. not interacting with other atoms).
