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.
Rutherford's atom compared to the model proposed by his student  Neils Bohr is very similar. Rutherford proposed a small positively  charged nucleus with electrons orbiting â¦ around it.Bohr improved on  this model by adding quantized energy levels to the orbits of  electrons around positively charged nucleus. the idea behind rutherfords atomic theory is that the atom has a central positive nucleus and negatively charged electrons, which move in orbits, surround it. most of th â¦ e atom is made up of empty space.
