How do isotopes differ from one another?
Quick Answer
Isotopes are atoms of the same element with different numbers of neutrons. They have the same atomic number but different mass numbers.
The Full Story
Isotopes belong to the same element because they have the same number of protons, but they differ in neutron count. Carbon-12 and carbon-14 are both carbon, yet carbon-14 is radioactive and used in radiocarbon dating. Some isotopes are stable, while others decay over time. Isotopes can affect mass-based measurements and nuclear behavior, but they usually have very similar chemistry. The discovery of isotopes helped explain why atomic masses are often not whole numbers.
Key Facts
1.Carbon-12 and carbon-14 are isotopes of carbon
2.Atomic number stays the same
3.Carbon-14 has a half-life of about 5,730 years
