TOPIC 2. THE STRUCTURE OF ATOMS
... Note how the electron arrangement in the Na+ ion is the same as for the Ne atom which has atomic number 10, one smaller than the Na atom. All the other members of the first group of elements in Table 2 (the alkali metals) also have just one more electron than a noble gas atom, and they all behave as ...
