Answer 2

Energetically electrons filled in 3d orbitals according to the Aufbau principle.

Explanation:

• Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom.
• When the electron returns to its original position, an electromagnetic wave is produced.
• Depending on the kind of atom and the amount of energy, this electromagnetic radiation can take the form of heat, light, ultraviolet, or other electromagnetic waves.

There are several ways of causing atoms to absorb energy. One way is to excite the atoms with electrical energy. We do this in neon signs.

• The electricity we put through the neon tubes will excite or add energy to the neon atoms. These electrons in these atoms are then in a high energy state.
• The electrons don't like to be in the high energy state and will fall back down into the low energy state giving off radiation which we see as light.
