  1. 1.

    While surveying the high-temperature surface of an exoplanet, an automated planetary probe reacts vaporized magnesium atoms with gaseous chlorine to synthesize a resilient heat-shielding material. The probe's sensors verify that each magnesium atom completely transfers two valence electrons to achieve a stable octet, while two individual chlorine atoms each absorb one electron. Which statement fundamentally describes the primary chemical bond holding this newly formed compound together?

    • A) It arises from the directional sharing of electron pairs that produces distinct, isolated molecular units.
    • B) It arises from nondirectional electrostatic attractions between positively charged magnesium cations and negatively charged chloride anions arranged in an extended crystal lattice.
    • C) It arises from a delocalized sea of valence electrons freely moving among closely packed neutral metal atoms.
    • D) It arises from weak, transient dipole attractions induced by instantaneous fluctuations in electron density between neutral atoms.
