Notice that you can easily find the number of electrons that an atom can accomodate on a particular shell, or energy level, by using the fact that each orbital can hold a maximum of two electrons.
In the case of the seventh shell, those
49
orbitals will hold a maximum of
no. of electrons
=
2
⋅
49
=
98 e
−
Explanation:
You can determine the number of orbitals you have in a particular shell by using the principal quantum number,
Answers & Comments
Answer:
no. of orbitals
=
n
2
So, for the first shell you have
no. of orbitals
=
1
2
=
1
For the second shell you have
no. of orbitals
=
2
2
=
4
In your case, the seventh shell will contain
no. of orbitals
=
7
2
=
49
