Isotopes, Ions, and Atomic Structure Flashcards
What is the atomic number?
The number of protons in an atom.
How do you calculate mass number?
Atomic number + number of neutrons.
How do you determine the charge of an ion?
Charge = protons - electrons.
What is the difference between an isotope and an ion?
Isotopes have different numbers of neutrons, ions have different numbers of electrons.
How do isotopes of the same element differ in physical properties?
They have different masses, affecting density and stability.
How are isotopes used in real-world applications?
In radiocarbon dating and medical imaging.
What is the most common isotope of hydrogen?
Protium (1 proton, 0 neutrons).
What are radioisotopes?
Isotopes that undergo radioactive decay.
How do you find the average atomic mass of an element?
Weighted average of all isotopes based on abundance.
What is a nuclear reaction involving isotopes?
Fission or fusion reactions.
