give at least 3 atoms with its isotopes and its application?

To find three atoms with their isotopes and applications, we can refer to the periodic table and look for elements with naturally occurring isotopes. Here are three examples:

1. Carbon (C):
- Isotopes: Carbon-12, Carbon-13, Carbon-14
- Applications:
- Carbon-12: Widely used in determining the relative atomic mass scale for other elements.
- Carbon-13: Used in nuclear magnetic resonance (NMR) spectroscopy to study molecular structures.
- Carbon-14: Used in radiocarbon dating to estimate the age of organic materials, such as archaeological artifacts or fossils.

2. Hydrogen (H):
- Isotopes: Hydrogen-1, Deuterium (Hydrogen-2), Tritium (Hydrogen-3)
- Applications:
- Hydrogen-1: Used as a fuel in various industries and in hydrodesulfurization processes in petroleum refining.
- Deuterium: Used as a tracer to investigate chemical reactions or study the behavior of biological molecules.
- Tritium: Used in self-luminous signs, exit signs, and markers, as well as a radioactive tracer in biomedical research.

3. Uranium (U):
- Isotopes: Uranium-238, Uranium-235, Uranium-234
- Applications:
- Uranium-238: Used as fuel in nuclear reactors for electricity generation.
- Uranium-235: Used in the production of nuclear energy and for the creation of nuclear weapons.
- Uranium-234: Used as a radiological tracer to determine the age of geological formations.

These are just a few examples, and many elements have different isotopes with various applications depending on their unique properties.
