Understanding Isotopes and Their Properties

Isotopes are atoms of the same element that have the same number of protons in their atomic nuclei but differ in the number of neutrons. This variation in neutron number affects the mass of the atom, resulting in different isotopes of the same element. In this article, we will explore the concept of isotopes, calculate the mass number of a tin isotope, and discuss the properties of isotopes.

What is the Mass Number of an Isotope of Tin?

To determine the mass number of an isotope of tin, we need to know the number of protons and neutrons in its atomic nucleus. The atomic number of tin is 50, which means it has 50 protons. The problem states that the isotope has 66 neutrons. The mass number of an atom is the sum of the number of protons and neutrons in its nucleus.

Calculating the Mass Number of Tin

The mass number of the tin isotope can be calculated as follows:

Mass number = Number of protons + Number of neutrons Mass number = 50 + 66 Mass number = 116

Therefore, the mass number of the tin isotope with 66 neutrons and 50 protons is 116.

Calculating the Number of Protons and Neutrons for $^{24}_{12}\text{Mg}$ and $^{88}_{38}\text{Sr}$

To calculate the number of protons and neutrons for $^{24}_{12}\text{Mg}$ and $^{88}_{38}\text{Sr}$ , we need to use the atomic number and mass number of each element.

Calculating the Number of Protons and Neutrons for $^{24}_{12}\text{Mg}$

The atomic number of magnesium is 12, which means it has 12 protons. The mass number of $^{24}_{12}\text{Mg}$ is 24. To calculate the number of neutrons, we subtract the number of protons from the mass number:

Number of neutrons = Mass number - Number of protons Number of neutrons = 24 - 12 Number of neutrons = 12

Therefore, the number of protons and neutrons for $^{24}_{12}\text{Mg}$ are 12 and 12, respectively.

Calculating the Number of Protons and Neutrons for $^{88}_{38}\text{Sr}$

The atomic number of strontium is 38, which means it has 38 protons. The mass number of $^{88}_{38}\text{Sr}$ is 88. To calculate the number of neutrons, we subtract the number of protons from the mass number:

Number of neutrons = Mass number - Number of protons Number of neutrons = 88 - 38 Number of neutrons = 50

Therefore, the number of protons and neutrons for $^{88}_{38}\text{Sr}$ are 38 and 50, respectively.

Why Do Isotopes of an Element Have Similar Properties?

Isotopes of an element have similar properties because they have the same number of protons in their atomic nuclei. The number of protons determines the chemical properties of an element, such as its reactivity and ability to form compounds with other elements. Since isotopes have the same number of protons, they exhibit similar chemical behavior.

However, isotopes can differ in their physical properties, such as mass and density. This is because the number of neutrons in an isotope affects its mass and density. For example, the isotope of tin with 66 neutrons and 50 protons has a mass number of 116, which is different from the mass number of other tin isotopes.

Conclusion

In conclusion, isotopes are atoms of the same element that have the same number of protons in their atomic nuclei but differ in the number of neutrons. The mass number of an isotope is the sum of the number of protons and neutrons in its nucleus. By calculating the mass number of a tin isotope and the number of protons and neutrons for $^{24}_{12}\text{Mg}$ and $^{88}_{38}\text{Sr}$ , we have demonstrated the importance of understanding the properties of isotopes.
