Respuesta :

the valence electrons determines the bonding of elements
bonding is based on the metallic characteristics of the element e.g
ionic bonding has to do with bonding between metallic and non metallic element  e.g. Na and CL
Na is a metal while Cl is a non metals
Na has 11 electron 2,8,1 while Cl has17 electrons 2,8,7,
 the compound NaCl is formed .by the two elements forming an octet structure
so without understanding  valence electrons you cannot understand bonding
