Here's a breakdown:
* Electron Shells: Electron shells are energy levels surrounding the nucleus of an atom where electrons reside. These shells are numbered starting with 1 (closest to the nucleus) and going up as you move further away.
* n1 (K Shell): This is the innermost shell and can hold a maximum of two electrons.
Key Points:
* Principal Quantum Number (n): The number "1" in "n1" represents the principal quantum number, which defines the energy level of the shell.
* Filling Order: Electrons fill shells starting with the lowest energy level (n=1, the K shell) and then move outward.
* Significance: The K shell is crucial for understanding atomic structure and chemical bonding.
Example:
* In the hydrogen atom, the single electron occupies the n1 (K) shell.
* In helium, both electrons fill the n1 (K) shell.
