Identify the suitable answer:

1. Which statement is FALSE according to the Bohr–Bury rules?

The L-shell can hold a maximum of 8 electrons.
The K-shell can hold a maximum of 2 electrons.
The outermost shell can contain a maximum of 18 electrons.
Electrons occupy shells from the one nearest to the nucleus.

2. Why do electrons occupy the K-shell before the L-shell?

The K-shell is the outermost shell.
The K-shell can accommodate more electrons than the L-shell.
The L-shell has lower energy than the K-shell.
The K-shell is nearest to the nucleus and is filled first.
