Sure, let's break down the details step by step:
1. Understanding Energy Levels in an Atom:
- In an atom, electrons are arranged in various energy levels or shells around the nucleus.
- Each energy level can hold a specific maximum number of electrons.
2. First Energy Level:
- The first energy level is the closest to the nucleus.
- It can hold a maximum of 2 electrons.
3. Second Energy Level:
- The second energy level can hold more electrons than the first.
- It has a capacity to hold up to 8 electrons.
4. Third Energy Level:
- The third energy level can accommodate even more electrons.
- It can hold up to 18 electrons.
Combining these details:
- First Energy Level: holds 2 electrons.
- Second Energy Level: holds 8 electrons.
- Third Energy Level: holds 18 electrons.
So, filling in the boxes:
- In an atom, the first energy level can hold 2 electrons.
- The second energy level can hold 8 electrons.
- The third energy level can hold 18 electrons.
This should give you the correct configuration for the electron capacity of the first three energy levels in an atom.
