Isotopes are a really interesting idea in chemistry!

They are different versions of the same element.

All isotopes have the same number of protons, but they have different numbers of neutrons.

This means they weigh different amounts, but they act similarly in chemical reactions.

Here are some common examples of isotopes:

1. Carbon Isotopes:

• Carbon-12 (C-12): This is the most common type of carbon. It is stable and makes up about 99% of the carbon found in nature.

• Carbon-14 (C-14): This version is radioactive. Scientists use it to date ancient materials, like fossils!

2. Hydrogen Isotopes:

• Protium (H-1): This is the most common type of hydrogen. It has one proton and no neutrons.

• Deuterium (H-2): This type has one neutron, which makes it heavier. It is used in nuclear reactors.

• Tritium (H-3): This is a radioactive form of hydrogen. It is used in hydrogen bombs and some types of glow-in-the-dark paint.

Learning about isotopes is important for scientists.

They help in many areas, like archaeology and medicine.

Isotopes are a fascinating part of studying atoms and molecules in chemistry!
