Answer:
Atomic attraction is the basis of a chemical bond. The differing actions of the outermost or valence electrons of atoms may be viewed as the cause of this attraction.
Explanation:
Bonding electrons: An electron involved in chemical bonding is referred to as a bonding electron. Chemical bond, a strong attraction between atoms, ions, or molecules, might be the subject here. Atoms exchanging electron pairs form a covalent or molecular connection. An attraction between the atomic orbitals of atoms in a molecule is called a bonding molecular orbital.
Lone-pair electrons: Lone pair, also known as a non-bonding pair, is an atom's valence electron pair that is not shared with another atom and does not participate in the creation of bonds. Atoms' outermost electron shell contains lone pairs.
Valence electrons: Valence refers to how many electrons an atom must obtain or lose in order to attain the octet or maintain stability. The vacant electrons in the outer shells are known as valence electrons.
Core electrons: For an atom of that element, all of the non-valence electrons are referred to as core electrons. The nucleus is strongly connected to the core electrons. As a result, unlike valence electrons, core electrons only contribute slightly to chemical bonding.
Hence, the term that describes electrons or pairs of electrons that are not involved in chemical bonding as core electrons.
Hence, the correct option is (d) Core electrons.
