A
Only s-orbital electrons
B
Valence electrons
C
Core electrons
D
All electrons
Verified step by step guidance1
Understand that chemical bonding involves the interaction between atoms to form molecules or compounds.
Recognize that electrons in an atom are arranged in different energy levels and orbitals, including core electrons (inner shells) and valence electrons (outermost shell).
Recall that core electrons are tightly bound to the nucleus and generally do not participate in bonding because they are not easily shared or transferred.
Identify valence electrons as the electrons in the outermost shell of an atom, which are the ones available to be shared, gained, or lost during bond formation.
Conclude that valence electrons are typically involved in forming bonds with other atoms, as they determine the chemical reactivity and bonding behavior of the element.
