The simplest model of metallic bonding is the "sea of electrons" model, which imagines that the atoms sit in a sea of valence electrons that are delocalized (spread out) over all the atoms.

(Check the table!) Mendeleev said that the atomic weights must not have been determined correctly, but they were correct.

(Again, consulting the gray shaded formulas in the first table will confirm this statement.) After careful study of the formulas in the table, it is also possible to conclude that none of the elements (except the unreactive noble gases) have smaller valences than H or Cl.

These diagrams display valence electrons as dots around the element's symbol and highlight their role in reactivity, with specific counts dictated by group placement in the periodic table. Notably, Group 1 has one valence electron, Group 2 has two, and Group 18 has eight.

We further assume the structure of the atom as a massive, positively charged nucleus, whose size is much smaller than that of the atom as a whole, surrounded by a vast open space in which move negatively charged electrons.
