The number of the column is the same as the number of valence electrons in all the elements placed in that column. The total number of electrons present in the valence shell of an atom is called valence electrons, and there is only one electron present in the valence shell of sodium (3s1). This means the electron configuration for Sodium is . Theor Sodium has 11 electrons: its atomic number is 11, so it has 11 protons; atoms are neutral, so this means sodium also has 11 electrons. When this occurs, the addition of 2 electrons brings selenium’s total electrons up to 36. 30 seconds . Two fluorine atoms, for example, can form a stable F 2 molecule in which each atom has an octet of valence electrons by sharing a pair of electrons.. A pair of oxygen atoms can form an O 2 molecule in which each atom has a total of eight valence electrons by sharing two pairs of electrons. the number of protons is the atomic number, which for sodium is 11. Therefore the valence number is 6. If a neutral Magnesium atom loses two electrons, what will its overall charge be? And it means that Sodium has one valence electron. …. C Lithium and Sodium. Sodium (Na) forms an ionic bond with Fluorine (F) to produce sodium fluoride (NaF). Valence electrons are the outermost electrons, and are the ones involved in bonding. An example of valence number is as follows: The chloride ion, Cl-, with a valence of one, has the capacity to unite with one atom of hydrogen or its equivalent, as in hydrogen chloride or sodium chloride.
