Answer: Valence electrons as dots around the symbol.
- A Valence electrons as dots around the symbol
- B Every single electron present in the entire atom
- C Electrons located within the nucleus itself
- D Neutrons present in the atomic nucleus
Correct answer: A. Valence electrons as dots around the symbol
Explanation: Lewis structures use dots to represent valence electrons around the chemical symbol.
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.
