What is and isotope pair?

An isotope pair refers to two or more atoms of the same element that have different numbers of neutrons in their nuclei. Isotopes of an element have the same number of protons, which determines the element's identity, but varying numbers of neutrons, which affects the atomic mass.

To find an isotope pair, you can follow these steps:

1. Identify the element: Determine the specific element for which you want to find an isotope pair. Each element is represented by its atomic symbol (e.g., H for hydrogen, C for carbon).

2. Look up the atomic number: Find the atomic number on the periodic table or by searching online. The atomic number represents the number of protons in the nucleus and determines the element's identity.

3. Check for isotopes: Locate the element on a reliable source, such as a periodic table or an isotope database. You should find a range of numbers below or above the atomic symbol of that element. These numbers represent the mass number or atomic mass.

4. Compare the mass numbers: Identify two or more isotopes of the element that have different mass numbers. For example, carbon has isotopes carbon-12 (mass number = 12) and carbon-14 (mass number = 14).

5. Note the name and properties: Make sure to record the names and properties of the isotope pair, if available. Some isotopes may have specific names due to their common occurrence or unique characteristics.

Remember that different isotopes may have different properties, such as stability or radioactivity, which can be important in various scientific applications.
