Which of the following is true when comparing two electrons which are in different shells of an atom?
When comparing two electrons in different shells of an atom, the following is true:
1. The electron in the outer shell has higher energy than the electron in the inner shell.
2. The electron in the outer shell experiences a weaker effective nuclear charge (attraction from the nucleus) than the electron in the inner shell.
3. The electron in the outer shell has a larger average distance from the nucleus compared to the electron in the inner shell.
4. The electron in the outer shell is more likely to participate in chemical reactions and form bonds compared to the electron in the inner shell.
5. The electron in the outer shell has a higher value of the principal quantum number (n) compared to the electron in the inner shell.
It is important to note that electrons in different shells have different characteristics due to their different energy levels and distances from the nucleus.
