Question

Predict whether an element with a valence of 8 is mostly likely form ionic bonds ,covalent bonds or no chemical bonds with other atoms explain

Answer 1

They are more likely not to form since they already have 8 valence electrons and don't require the need of other atoms to create a bond with

Answer 2

An element with a valence of 8 are most likely noble gases (He, Ne, Ar, etc) which means they're already stable so they dont need to undergo chemical bonds with another atom because they already have a full valence shell.
