How does the electronic structure of a metal differ from a non-metal?

Answer 1

In the electronic configuration when the last shell is filled with 1,2 or 3 electrons then the element tends to give out electrons.

when elements give out these 1,2 or 3 electrons it becomes positive

these positive atoms are metals

Answer 2

alkali metals are all s block atoms, transistion metals d block and non metals p block. Meaning that the outer orbitals in each case are s, d, p respectively

Answer 3

Each chemical element has a specific electron configuration in the neutral state of the atom.
