The energy is higher.
valence electrons are the electrons in the outermost energy level
The second energy level can hold a maximum of 8 electrons. Magnesium has 12 electrons, so in its second energy level, there will be 8 electrons (2 in the first energy level and 8 in the second energy level).
In general, electrons further from the nucleus will have more energy than electrons closer to the nucleus.
The electrons and energy level are inversely related. Electrons are positively charged while the energy level is negatively charged which will result into a direct effect in the energy level when electrons move. .
A magnetron is a high-power, high frequency vacuum tube. The magnetron is the source of radio-frequency energy in RADAR systems and in the microwave oven in your kitchen, for example.
Eventually - over time the magnetron loses its ability to produce sufficient quantities of electrons (the source of the microwaves cooking ability) to cook food properly.

The energy of the valence electrons is greater than the energy of the core electrons.
Imagine a tuned cavity i.e. a bell. When it is struck, it provides a sound wave of fixed frequency. If it is struck several times a second, it provides the same frequency at a much higher volume. The striking of the bell is known as the pulse repetition frequency (PRF) and it is this that dictates the power output of a magnetron. The dimensions of the cavities govern the output frequency. Instead of striking a magnetron, it is pulsed across its anode and cathode by a high DC voltage. This is the energy input that equates to the striking of the bell. The gap between the cathode and anode is a vacuum. Electrons being emitted by the heated cathode each time it is pulsed or 'struck' transfer the energy to the cavities. These electrons bunch in reaction to the tuned frequency of the cavities, forming spokes circulating the cathode. Eventually, the electrons strike the anode and cause the cavities to 'ring' at the tuned frequency. One of the cavities has a loop that extracts the energy into a coax/waveguide.
The valence electrons
The energy of the valence electrons is greater than the energy of the core electrons.
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher energy levels.
To test a magnetron in a microwave oven, you can use a multimeter set to the resistance or continuity function. Disconnect the magnetron from the oven and touch the multimeter probes to the terminals on the magnetron. If there is no continuity or the resistance reading is significantly different from the specified range, the magnetron may be faulty.
