____-Row Elements: electrons fill 1s orbital
first
______-Row Elements: electrons also fill 2s and three 2p orbitals.
second
Maximum of _ valence e- for elements in second row.
8
___ ___ result from the transfer of e- from one element to another, leading to electrostatic attraction of a cation and an anion.
