Answer:

[tex]\boxed {\boxed {\sf Isotopes}}[/tex]

Explanation:

Atoms of the same element all have the same atomic number (number of protons). However, they can have different numbers of neutrons.

If an atom gains or loses a neutron, it becomes a different isotope of the element.

For example, let's look at carbon.

Carbon-12

  • 6 protons and 6 neutrons
  • The most abundant isotope

Carbon-14

  • 6 protons and 8 neutrons
  • Used in radioactive dating of previously living things.
