Sodium is the seventh most abundant element and fifth most abundant metal on the earth. The Earth’s crust contains around 2.27 % of sodium [3]. About 1.08×104 milligrams per liter of sodium is estimated to be present in ocean water in the form of brine. It is never found as a pure element due to its high reactivity [4].

Jan 20, 2020 · So, as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. Electronegativity increases as you move from left to right across a period on the periodic table. While developing the Periodic Table, there were a few instances where Mendeléev had to place an element with a slightly greater atomic mass before Similarly, you will find that the elements present in any one group have the same number of valence electrons. For example, elements fluorine (F)...1. Period K L M N O P Q; Number Symbol Name 1s 2s 2p 3s 3p 3d 4s 4p 4d 4f 5s 5p 5d 5f 6s 6p 6d 6f 7s 7p; 1: H: Hydrogen: 1 : 2: He: Helium: 2

  20. It is a period or row that is energy level five or more, below calcium on the periodic table.. Two valence electrons places the element in the alkaline earth family or group II A along with calcium.
  21. However it is also repelled by the charge on the inner two electrons. Electrons in the 1s orbital are much closer to the nucleus than any electrons in the 2 s or 2 p orbital. The two inner electrons in the 1 s orbital screen the third electron from the full effect of the nuclear +3 charge.
