Atoms and Isotopes: Exploring the World of Elements

What are atoms whose atomic number are the same but whose mass numbers are different called?

A. Alpha particles

B. Ions

C. Beta particles

D. Isotopes

Answer:

Atoms whose atomic number are the same but whose mass numbers are different are called Isotopes.

Understanding Isotopes

Isotopes are elements with the same atomic number but different mass numbers. They play a crucial role in the world of chemistry and provide us with valuable information about the properties of different elements.

For example, Protium, Deuterium, and Tritium are isotopes of hydrogen, each with varying numbers of neutrons in their nuclei. Similarly, carbon isotopes C-14 and C-12 have different mass numbers due to the differing number of neutrons.

Isotopes are commonly used in various fields such as medicine, environmental science, and archaeology to study and analyze different materials and substances.

Understanding isotopes can offer insights into the behavior and characteristics of elements, making them a fascinating aspect of the world of atoms.
