Question

19 sep use models why does the number of electrons in each principal energy shell increase as the number of the shell increases? the number of electrons increase because

Explanation:

As the principal energy shell number (n) increases, the number of available orbitals increases. Each orbital can hold a maximum of 2 electrons. The number of orbitals in a shell is given by $n^{2}$, so more orbitals mean more electrons can be accommodated.

Answer:

As the principal energy - shell number increases, the number of available orbitals increases (number of orbitals = $n^{2}$), allowing more electrons to be present in the shell.
