The characteristics of two different types of reactions are shown below:

Reaction A: Protons are gained or lost by the atom of an element.
Reaction B: Electrons are lost by the atoms of an element.

Which statement is true about the two reactions?

Valence electrons are not involved in both Reaction A and Reaction B.
Valence electrons are involved in Reaction B but not in Reaction A.
Valence electrons are involved in both Reaction A and Reaction B.
Valence electrons are involved in Reaction A but not in Reaction B.

Given what we know about these reactions, we can confirm that Valence electrons are involved in Reaction B but not in Reaction A.

What is a Valence electron?

  • A valence electron is an electron located on the outermost shell of the atom's electron cloud.
  • All elements seek to complete this outermost shell in order to achieve a level of stability close to that of a noble gas.
  • Therefore, these will not have an effect on the loss of a proton, since this can happen only through nuclear fission or radioactive decay of the atom.

Therefore, due to the definition and use of valence electrons and the way that an atom can go about losing a proton, we can confirm that Valence electrons are involved in Reaction B but not in Reaction A.
