How many electrons can 3rd shell hold?

Answer 1

In (3s2 3p6 3d10) = 2 + 6 + 10 = 18 electrons in the 3rd shell (3(s+p+d))

Answer 2

The third shell can hold a maximum of 18 electrons. The third shell consists of one s orbital (2 electrons), three p orbitals (6 electrons), and five d orbitals (10 electrons).

Answer 3

The third electron cloud, like the second, can hold 8 electrons. 2 in the s orbital, 6 in the p.
