Unit 1: Topic 1 Isotopes Flashcards
1
Q
Q: How do isotopes affect atomic properties?
A
A: Isotopes have the same chemical properties (same electron configuration) but different physical properties (e.g., mass, density).
2
Q
Q: How do you represent isotopes?
A
A: - IUPAC notation: AZX (e.g 14/6 C)
Hyphen notation: X-A (e.g., Carbon-14).
3
Q
Q: Define relative atomic mass.
A
A: The weighted average mass of an element’s isotopes compared to 1/12 the mass of a carbon-12 atom.
