Which of the following best describes what an electron domain consists of?
A
Only the bonding electrons between two atoms
B
A single electron in an atomic orbital
C
A region in a molecule where electrons are likely to be found, including lone pairs and bonds
D
All electrons in the outermost shell of an atom
Verified step by step guidance1
Understand that an electron domain refers to a region around a central atom where electrons are most likely to be found.
Recognize that electron domains include both bonding pairs of electrons (shared between atoms) and lone pairs (non-bonding electrons localized on one atom).
Note that a single electron in an atomic orbital does not fully represent an electron domain, as domains typically involve pairs or regions of electron density.
Realize that electron domains are not limited to only bonding electrons but also include lone pairs, making them broader than just bonds.
Conclude that the best description of an electron domain is: 'A region in a molecule where electrons are likely to be found, including lone pairs and bonds.'
