Answer: One atom (the donor/Lewis base).
- A One atom (the donor/Lewis base)
- B Both atoms as frequently described
- C The solvent in most textbook accounts
- D An outside source during normal conditions
Correct answer: A. One atom (the donor/Lewis base)
Explanation: In a coordinate/dative bond, one atom (Lewis base/donor) donates both electrons to a Lewis acid acceptor.
VSEPR theory predicts molecular shape from the number of bonding and lone electron pairs around the central atom.
Concept context
Understand how atoms join to form molecules. Covers ionic and covalent bonding, VSEPR theory, hybridization (sp, sp², sp³), molecular orbital theory, bond polarity, and intermolecular forces like hydrogen bonding.
