How many electron shells/orbitals does the element Krypton (Kr) have?

Krypton has 4 orbital shells

Extra Information:

Krypton has 36 electrons which are arranged in these 4 orbit shells,

The order in which electrons are arranged in these shells is 2,8,18,8

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the right answer is c i just did the question.
