How do you determine how many electron energy levels an element has

36

Explanation:

Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.

Explanation:

The maximum number of electrons that can occupy a specific energy level can be found using the following formula: Electron Capacity = 2 n 2 The variable n represents the Principal Quantum Number, the number of the energy level in question.
