1.9 Describe isotopes as different atoms of the same element containing the same number of protons but different numbers of neutrons in their nuclei Flashcards
What are isotopes?
Isotopes are variations of the same element that possess the same number of protons but differ in the number of neutrons in their nuclei.
What defines an element?
The number of protons in an atom’s nucleus defines which element it is.
How do isotopes differ?
Isotopes of a given element can vary in the number of neutrons present in the nucleus.
What determines atomic mass?
The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus.
How do isotopes affect physical properties?
Different isotopes can have different physical properties like density, melting point, or boiling point due to variations in atomic mass.
Do isotopes have similar chemical properties?
Yes, isotopes generally have similar chemical properties because the number of electrons is the same for all isotopes of a given element.
