The negative (oxygen) end of water is attracted to the positive sodium ion in the salt, extracts it from the lattice and more water molecules surround it (i.e. dissolve it). The same is true for the positive (hydrogen) end of water and the negative chloride ion in the salt.
According to nitrogen's electron configuration table, an atom of nitrogen contains two electrons in its first energy level (both in the s sub-shell) and five electrons in its second energy level (two in the s sub-shell and three in the p sub-shell). A more accurate Bohr model of a nitrogen atom could look like this: In the refined Bohr model, a nitrogen atom has a central nucleus, composed of seven protons and seven neutrons, surrounded by seven electrons.
Hydrogen Atom. Hydrogen atom is the first element in the periodic table. Hydrogen atom has one electron and one proton. Therefore, it has the electron configuration of 1s 1.It only has one electron filled in the s-sub orbital where two electrons can be accommodated.Therefore, hydrogen atom is unstable and very reactive in order to obtain a stable electron configuration. Hydrogen atom has one proton and one electron, whereas hydrogen ion has one proton, but no electrons. â¢ Because of the release of one electron, the hydrogen ion radius differs from the atomic radius. â¢ Hydrogen atom is more reactive than the ion because it is more unstable.
