What determines chemical bonding characteristics?
the configuration of the outermost orbital
the configuration of the nucleus
the atomic weight of an atom
the type of material
the number of neutrons

Option (a) is the correct answer.

Explanation:

A chemical bonding in a substance occurs when there is exchange of electrons between the atoms. These electrons are present in the outermost orbital are actually away from the nucleus of the atom.

Due to which there is no force of attraction between nucleus or valence electrons. Hence, it is easy for the outermost orbital to lose electron.

Whereas nucleus of an atom contains neutrons and protons. And, changes in the nucleus of an atom leads to nuclear reactions.

Therefore, we can conclude that the configuration of the outermost orbital determines chemical bonding characteristics.

i'm pretty sure its b i might be wrong though!

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d
