Question

What is the total number of completely filled sublevels found in the atom of krypton in the ground state?

Answer 1

Krypton in the ground state has a total of 4 completely filled sublevels, which are 1s, 2s, 2p, and 3s.

Step-by-step explanation:

In the ground state, krypton has a total of 4 completely filled sublevels. The electron configuration for krypton is: 1s²2s²2p⁶3s²3p⁶3d¹4s²4p⁶. The completely filled sublevels are 1s, 2s, 2p, and 3s.

Answer 2

There are a total of eight completely filled sublevels in Krypton in its ground states. These sublevels are:
1s, 2s, 2p, 3s, 3p, 3d, 4s and 4p

This configuration indicates that Krypton is stable as it does not need to gain or lose any electrons to complete its octet. This is why Krypton is a noble gas.
