Understanding Atomic Structure
To determine the number of protons, electrons, and neutrons in an element, we can use its atomic number and atomic mass. Let’s break this down for the element with an atomic mass of 197 and an atomic number of 79.
1. Protons
- The atomic number of an element indicates the number of protons in its nucleus.
- For this element, the atomic number is 79.
- Therefore, the number of protons is:
- 79 protons
2. Electrons
- In a neutral atom, the number of electrons equals the number of protons.
- Since our element has 79 protons, it also has:
- 79 electrons
3. Neutrons
- The atomic mass (rounded to the nearest whole number) gives the total number of protons and neutrons in the nucleus.
- To find the number of neutrons, use the formula:
- Neutrons = Atomic Mass - Protons
- For our element:
- Neutrons = 197 - 79
- Neutrons = 118
- Therefore, the number of neutrons is:
- 118 neutrons
Summary
- Protons: 79
- Electrons: 79
- Neutrons: 118
This information about protons, electrons, and neutrons is fundamental in understanding the properties and behavior of the element.
